GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 393) = 97071
GCD(247, 393) = ( 247 x 393 ) / 97071
= 247 / 393
= 247
Step2:
LCM(1, 962) = 962
GCD(1, 962) = ( 1 x 962 ) / 962
= 1 / 962
= 1
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 247, 393, 962, 861 is 1
