Given numbers are 356, 342, 645, 862

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

Apply this formula for all numbers.

Step1:

LCM(356, 342) = 60876

GCD(356, 342) = ( 356 x 342 ) / 60876

= 356 / 342

= 356

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

So, Greatest Common Divisor of 356, 342, 645, 862 is 1
