GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 281) = 137971
GCD(491, 281) = ( 491 x 281 ) / 137971
= 491 / 281
= 491
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 719) = 719
GCD(1, 719) = ( 1 x 719 ) / 719
= 1 / 719
= 1
So, Greatest Common Divisor of 491, 281, 649, 719 is 1
