GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 675) = 436725
GCD(647, 675) = ( 647 x 675 ) / 436725
= 647 / 675
= 647
Step2:
LCM(1, 149) = 149
GCD(1, 149) = ( 1 x 149 ) / 149
= 1 / 149
= 1
Step3:
LCM(1, 331) = 331
GCD(1, 331) = ( 1 x 331 ) / 331
= 1 / 331
= 1
So, Greatest Common Divisor of 647, 675, 149, 331 is 1
