Given numbers are 672, 153, 556, 486
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 153) = 34272
GCD(672, 153) = ( 672 x 153 ) / 34272
= 672 / 153
= 672
Step2:
LCM(3, 556) = 1668
GCD(3, 556) = ( 3 x 556 ) / 1668
= 3 / 556
= 3
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 672, 153, 556, 486 is 1
