GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 476) = 307972
GCD(647, 476) = ( 647 x 476 ) / 307972
= 647 / 476
= 647
Step2:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
Step3:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
So, Greatest Common Divisor of 647, 476, 159, 397 is 1
