GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 891) = 43659
GCD(147, 891) = ( 147 x 891 ) / 43659
= 147 / 891
= 147
Step2:
LCM(3, 729) = 729
GCD(3, 729) = ( 3 x 729 ) / 729
= 3 / 729
= 3
Step3:
LCM(3, 155) = 465
GCD(3, 155) = ( 3 x 155 ) / 465
= 3 / 155
= 3
So, Greatest Common Divisor of 147, 891, 729, 155 is 1
