Given numbers are 731, 649, 131, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(731, 649) = 474419
GCD(731, 649) = ( 731 x 649 ) / 474419
= 731 / 649
= 731
Step2:
LCM(1, 131) = 131
GCD(1, 131) = ( 1 x 131 ) / 131
= 1 / 131
= 1
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 731, 649, 131, 721 is 1
