Given numbers are 721, 715, 294, 554
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 715) = 515515
GCD(721, 715) = ( 721 x 715 ) / 515515
= 721 / 715
= 721
Step2:
LCM(1, 294) = 294
GCD(1, 294) = ( 1 x 294 ) / 294
= 1 / 294
= 1
Step3:
LCM(1, 554) = 554
GCD(1, 554) = ( 1 x 554 ) / 554
= 1 / 554
= 1
So, Greatest Common Divisor of 721, 715, 294, 554 is 1
