GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 207) = 21735
GCD(945, 207) = ( 945 x 207 ) / 21735
= 945 / 207
= 945
Step2:
LCM(9, 458) = 4122
GCD(9, 458) = ( 9 x 458 ) / 4122
= 9 / 458
= 9
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 945, 207, 458, 649 is 1
