GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 106) = 34238
GCD(646, 106) = ( 646 x 106 ) / 34238
= 646 / 106
= 646
Step2:
LCM(2, 648) = 648
GCD(2, 648) = ( 2 x 648 ) / 648
= 2 / 648
= 2
Step3:
LCM(2, 274) = 274
GCD(2, 274) = ( 2 x 274 ) / 274
= 2 / 274
= 2
So, Greatest Common Divisor of 646, 106, 648, 274 is 2
