Given numbers are 157, 855, 510, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 855) = 134235
GCD(157, 855) = ( 157 x 855 ) / 134235
= 157 / 855
= 157
Step2:
LCM(1, 510) = 510
GCD(1, 510) = ( 1 x 510 ) / 510
= 1 / 510
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 157, 855, 510, 638 is 1
