GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 931) = 41895
GCD(315, 931) = ( 315 x 931 ) / 41895
= 315 / 931
= 315
Step2:
LCM(7, 897) = 6279
GCD(7, 897) = ( 7 x 897 ) / 6279
= 7 / 897
= 7
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 315, 931, 897, 847 is 1
