Given numbers are 663, 765, 247, 613
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 765) = 9945
GCD(663, 765) = ( 663 x 765 ) / 9945
= 663 / 765
= 663
Step2:
LCM(51, 247) = 12597
GCD(51, 247) = ( 51 x 247 ) / 12597
= 51 / 247
= 51
Step3:
LCM(1, 613) = 613
GCD(1, 613) = ( 1 x 613 ) / 613
= 1 / 613
= 1
So, Greatest Common Divisor of 663, 765, 247, 613 is 1
