Given numbers are 668, 630, 889, 136
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 630) = 210420
GCD(668, 630) = ( 668 x 630 ) / 210420
= 668 / 630
= 668
Step2:
LCM(2, 889) = 1778
GCD(2, 889) = ( 2 x 889 ) / 1778
= 2 / 889
= 2
Step3:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
So, Greatest Common Divisor of 668, 630, 889, 136 is 1
