Given numbers are 157, 685, 139, 488
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 685) = 107545
GCD(157, 685) = ( 157 x 685 ) / 107545
= 157 / 685
= 157
Step2:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
Step3:
LCM(1, 488) = 488
GCD(1, 488) = ( 1 x 488 ) / 488
= 1 / 488
= 1
So, Greatest Common Divisor of 157, 685, 139, 488 is 1
