GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 936) = 605592
GCD(647, 936) = ( 647 x 936 ) / 605592
= 647 / 936
= 647
Step2:
LCM(1, 753) = 753
GCD(1, 753) = ( 1 x 753 ) / 753
= 1 / 753
= 1
Step3:
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
= 1 / 218
= 1
So, Greatest Common Divisor of 647, 936, 753, 218 is 1
