Steps to Calculate GCD of 758, 103, 449, 646 using LCM Formula
Given numbers are 758, 103, 449, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(758, 103) = 78074
GCD(758, 103) = ( 758 x 103 ) / 78074
= 758 / 103
= 758
Step2:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 758, 103, 449, 646 is 1
