Given numbers are 156, 403, 558, 672
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 403) = 4836
GCD(156, 403) = ( 156 x 403 ) / 4836
= 156 / 403
= 156
Step2:
LCM(13, 558) = 7254
GCD(13, 558) = ( 13 x 558 ) / 7254
= 13 / 558
= 13
Step3:
LCM(1, 672) = 672
GCD(1, 672) = ( 1 x 672 ) / 672
= 1 / 672
= 1
So, Greatest Common Divisor of 156, 403, 558, 672 is 1
