Given numbers are 680, 842, 959, 157

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

Apply this formula for all numbers.

Step1:

LCM(680, 842) = 286280

GCD(680, 842) = ( 680 x 842 ) / 286280

= 680 / 842

= 680

Step2:

LCM(2, 959) = 1918

GCD(2, 959) = ( 2 x 959 ) / 1918

= 2 / 959

= 2

Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

So, Greatest Common Divisor of 680, 842, 959, 157 is 1
