Given numbers are 642, 372, 797, 660

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

Apply this formula for all numbers.

Step1:

LCM(642, 372) = 39804

GCD(642, 372) = ( 642 x 372 ) / 39804

= 642 / 372

= 642

Step2:

LCM(6, 797) = 4782

GCD(6, 797) = ( 6 x 797 ) / 4782

= 6 / 797

= 6

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 642, 372, 797, 660 is 1
