GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 427) = 169519
GCD(397, 427) = ( 397 x 427 ) / 169519
= 397 / 427
= 397
Step2:
LCM(1, 650) = 650
GCD(1, 650) = ( 1 x 650 ) / 650
= 1 / 650
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 397, 427, 650, 891 is 1
