Given numbers are 847, 638, 840, 793
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 638) = 49126
GCD(847, 638) = ( 847 x 638 ) / 49126
= 847 / 638
= 847
Step2:
LCM(11, 840) = 9240
GCD(11, 840) = ( 11 x 840 ) / 9240
= 11 / 840
= 11
Step3:
LCM(1, 793) = 793
GCD(1, 793) = ( 1 x 793 ) / 793
= 1 / 793
= 1
So, Greatest Common Divisor of 847, 638, 840, 793 is 1
