GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(744, 646) = 240312
GCD(744, 646) = ( 744 x 646 ) / 240312
= 744 / 646
= 744
Step2:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
Step3:
LCM(1, 529) = 529
GCD(1, 529) = ( 1 x 529 ) / 529
= 1 / 529
= 1
So, Greatest Common Divisor of 744, 646, 621, 529 is 1
