GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 863) = 213161
GCD(247, 863) = ( 247 x 863 ) / 213161
= 247 / 863
= 247
Step2:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
Step3:
LCM(1, 949) = 949
GCD(1, 949) = ( 1 x 949 ) / 949
= 1 / 949
= 1
So, Greatest Common Divisor of 247, 863, 688, 949 is 1
