Given numbers are 349, 689, 435, 103
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(349, 689) = 240461
GCD(349, 689) = ( 349 x 689 ) / 240461
= 349 / 689
= 349
Step2:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
Step3:
LCM(1, 103) = 103
GCD(1, 103) = ( 1 x 103 ) / 103
= 1 / 103
= 1
So, Greatest Common Divisor of 349, 689, 435, 103 is 1
