GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 164) = 26404
GCD(644, 164) = ( 644 x 164 ) / 26404
= 644 / 164
= 644
Step2:
LCM(4, 948) = 948
GCD(4, 948) = ( 4 x 948 ) / 948
= 4 / 948
= 4
Step3:
LCM(4, 413) = 1652
GCD(4, 413) = ( 4 x 413 ) / 1652
= 4 / 413
= 4
So, Greatest Common Divisor of 644, 164, 948, 413 is 1
