GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 624) = 201552
GCD(646, 624) = ( 646 x 624 ) / 201552
= 646 / 624
= 646
Step2:
LCM(2, 294) = 294
GCD(2, 294) = ( 2 x 294 ) / 294
= 2 / 294
= 2
Step3:
LCM(2, 170) = 170
GCD(2, 170) = ( 2 x 170 ) / 170
= 2 / 170
= 2
So, Greatest Common Divisor of 646, 624, 294, 170 is 2
