Given numbers are 642, 153, 925

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

Apply this formula for all numbers.

Step1:

LCM(642, 153) = 32742

GCD(642, 153) = ( 642 x 153 ) / 32742

= 642 / 153

= 642

Step2:

LCM(3, 925) = 2775

GCD(3, 925) = ( 3 x 925 ) / 2775

= 3 / 925

= 3

So, Greatest Common Divisor of 642, 153, 925 is 1
