Given numbers are 751, 213, 644

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

Apply this formula for all numbers.

Step1:

LCM(751, 213) = 159963

GCD(751, 213) = ( 751 x 213 ) / 159963

= 751 / 213

= 751

Step2:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 751, 213, 644 is 1
