Given numbers are 151, 855, 742

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

Apply this formula for all numbers.

Step1:

LCM(151, 855) = 129105

GCD(151, 855) = ( 151 x 855 ) / 129105

= 151 / 855

= 151

Step2:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

So, Greatest Common Divisor of 151, 855, 742 is 1
