Given numbers are 139, 642, 470

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

Apply this formula for all numbers.

Step1:

LCM(139, 642) = 89238

GCD(139, 642) = ( 139 x 642 ) / 89238

= 139 / 642

= 139

Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 139, 642, 470 is 1
