Given numbers are 672, 814, 389, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 814) = 273504
GCD(672, 814) = ( 672 x 814 ) / 273504
= 672 / 814
= 672
Step2:
LCM(2, 389) = 778
GCD(2, 389) = ( 2 x 389 ) / 778
= 2 / 389
= 2
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 672, 814, 389, 628 is 1
