GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 306) = 5814
GCD(646, 306) = ( 646 x 306 ) / 5814
= 646 / 306
= 646
Step2:
LCM(34, 112) = 1904
GCD(34, 112) = ( 34 x 112 ) / 1904
= 34 / 112
= 34
Step3:
LCM(2, 672) = 672
GCD(2, 672) = ( 2 x 672 ) / 672
= 2 / 672
= 2
So, Greatest Common Divisor of 646, 306, 112, 672 is 2
