Given numbers are 663, 947, 863, 137
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 947) = 627861
GCD(663, 947) = ( 663 x 947 ) / 627861
= 663 / 947
= 663
Step2:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
Step3:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
So, Greatest Common Divisor of 663, 947, 863, 137 is 1
