Given numbers are 645, 692, 377, 857

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

Apply this formula for all numbers.

Step1:

LCM(645, 692) = 446340

GCD(645, 692) = ( 645 x 692 ) / 446340

= 645 / 692

= 645

Step2:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

Step3:

LCM(1, 857) = 857

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

= 1 / 857

= 1

So, Greatest Common Divisor of 645, 692, 377, 857 is 1
