Given numbers are 215, 713, 642

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

Apply this formula for all numbers.

Step1:

LCM(215, 713) = 153295

GCD(215, 713) = ( 215 x 713 ) / 153295

= 215 / 713

= 215

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 215, 713, 642 is 1
