Given numbers are 520, 674, 449, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 674) = 175240
GCD(520, 674) = ( 520 x 674 ) / 175240
= 520 / 674
= 520
Step2:
LCM(2, 449) = 898
GCD(2, 449) = ( 2 x 449 ) / 898
= 2 / 449
= 2
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 520, 674, 449, 678 is 1
