Given numbers are 349, 681, 490, 671
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(349, 681) = 237669
GCD(349, 681) = ( 349 x 681 ) / 237669
= 349 / 681
= 349
Step2:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
Step3:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
So, Greatest Common Divisor of 349, 681, 490, 671 is 1
