Given numbers are 642, 127, 354

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

Apply this formula for all numbers.

Step1:

LCM(642, 127) = 81534

GCD(642, 127) = ( 642 x 127 ) / 81534

= 642 / 127

= 642

Step2:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

So, Greatest Common Divisor of 642, 127, 354 is 1
