Given numbers are 647, 384, 921, 751
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 384) = 248448
GCD(647, 384) = ( 647 x 384 ) / 248448
= 647 / 384
= 647
Step2:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
Step3:
LCM(1, 751) = 751
GCD(1, 751) = ( 1 x 751 ) / 751
= 1 / 751
= 1
So, Greatest Common Divisor of 647, 384, 921, 751 is 1
