Given numbers are 851, 758, 644

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

Apply this formula for all numbers.

Step1:

LCM(851, 758) = 645058

GCD(851, 758) = ( 851 x 758 ) / 645058

= 851 / 758

= 851

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 851, 758, 644 is 1
