Given numbers are 643, 642, 925, 776

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

Apply this formula for all numbers.

Step1:

LCM(643, 642) = 412806

GCD(643, 642) = ( 643 x 642 ) / 412806

= 643 / 642

= 643

Step2:

LCM(1, 925) = 925

GCD(1, 925) = ( 1 x 925 ) / 925

= 1 / 925

= 1

Step3:

LCM(1, 776) = 776

GCD(1, 776) = ( 1 x 776 ) / 776

= 1 / 776

= 1

So, Greatest Common Divisor of 643, 642, 925, 776 is 1
