Given numbers are 213, 672, 279, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 672) = 47712
GCD(213, 672) = ( 213 x 672 ) / 47712
= 213 / 672
= 213
Step2:
LCM(3, 279) = 279
GCD(3, 279) = ( 3 x 279 ) / 279
= 3 / 279
= 3
Step3:
LCM(3, 158) = 474
GCD(3, 158) = ( 3 x 158 ) / 474
= 3 / 158
= 3
So, Greatest Common Divisor of 213, 672, 279, 158 is 1
