Given numbers are 453, 995, 644

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

Apply this formula for all numbers.

Step1:

LCM(453, 995) = 450735

GCD(453, 995) = ( 453 x 995 ) / 450735

= 453 / 995

= 453

Step2:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 453, 995, 644 is 1
