Given numbers are 951, 780, 997, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(951, 780) = 247260
GCD(951, 780) = ( 951 x 780 ) / 247260
= 951 / 780
= 951
Step2:
LCM(3, 997) = 2991
GCD(3, 997) = ( 3 x 997 ) / 2991
= 3 / 997
= 3
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 951, 780, 997, 638 is 1
