Given numbers are 420, 931, 893, 896
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 931) = 55860
GCD(420, 931) = ( 420 x 931 ) / 55860
= 420 / 931
= 420
Step2:
LCM(7, 893) = 6251
GCD(7, 893) = ( 7 x 893 ) / 6251
= 7 / 893
= 7
Step3:
LCM(1, 896) = 896
GCD(1, 896) = ( 1 x 896 ) / 896
= 1 / 896
= 1
So, Greatest Common Divisor of 420, 931, 893, 896 is 1
