The number 61 is an integer that falls between the numbers 60 and 62. It can be written as a numeral using the digits “6” and “1”, or it can be written in words as sixty-one. This number has many uses, including its use in mathematics, sports, music theory, science and technology applications.

In mathematics 61 is an odd composite number composed of three distinct prime numbers multiplied together: 3 x 5 x 11 = 61. It has six divisors: 1, 3 ,5 ,11 ,15 &61; making it a semi-prime or bi-prime number since two of its factors are prime numbers (3 & 5).

In addition to being used for basic arithmetic operations such as multiplication tables or counting money; this numerical value may also represent angles when working with geometry problems involving circles where 360° equals one complete revolution around the circle’s circumference.

In sports some teams have chosen to adopt this numeric figure into their team logos while others have adopted uniforms that bear this numerical insignia on them – most notably Major League Baseball’s San Francisco Giants who feature #61 on their jerseys worn by players like pitcher Madison Bumgarner during games played at AT&T Park Stadium located within The City By The Bay.

Furthermore musicians often refer to “the key of C major” which contains seven notes (C D E F G A B) but also includes additional sharps (#) and flats (b); thus making up what we know today as scales containing twelve tones per octave – all beginning from middle C which bears note frequency 261 Hz – hence why musical notation includes reference points labeled “Middle C#/Db = 261Hz”.

Finally scientists across various disciplines rely heavily upon measurements made via scientific instruments calibrated with units suchas meters/second squared [m/sec2]; wherein acceleration due gravity near the Earth’s surface equates to 981m/sec2 – otherwise referred to scientifically speaking simply known only by its numerical designation: g=981m/sec2.
