Given numbers are 742, 723, 518, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 723) = 536466
GCD(742, 723) = ( 742 x 723 ) / 536466
= 742 / 723
= 742
Step2:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 742, 723, 518, 247 is 1
