Given numbers are 695, 450, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(695, 450) = 62550
GCD(695, 450) = ( 695 x 450 ) / 62550
= 695 / 450
= 695
Step2:
LCM(5, 638) = 3190
GCD(5, 638) = ( 5 x 638 ) / 3190
= 5 / 638
= 5
So, Greatest Common Divisor of 695, 450, 638 is 1
