Given numbers are 742, 715, 857

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

Apply this formula for all numbers.

Step1:

LCM(742, 715) = 530530

GCD(742, 715) = ( 742 x 715 ) / 530530

= 742 / 715

= 742

Step2:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 742, 715, 857 is 1
