Given numbers are 978, 280, 955

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(978, 280) = 136920

GCD(978, 280) = ( 978 x 280 ) / 136920

= 978 / 280

= 978

Step2:

LCM(2, 955) = 1910

GCD(2, 955) = ( 2 x 955 ) / 1910

= 2 / 955

= 2

So, Greatest Common Divisor of 978, 280, 955 is 1
