Given numbers are 379, 651, 78, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(379, 651) = 246729
GCD(379, 651) = ( 379 x 651 ) / 246729
= 379 / 651
= 379
Step2:
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
= 1 / 78
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 379, 651, 78, 644 is 1
