Given numbers are 847, 130, 231, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 130) = 110110
GCD(847, 130) = ( 847 x 130 ) / 110110
= 847 / 130
= 847
Step2:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 847, 130, 231, 778 is 1
