Given numbers are 344, 686, 526, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(344, 686) = 117992
GCD(344, 686) = ( 344 x 686 ) / 117992
= 344 / 686
= 344
Step2:
LCM(2, 526) = 526
GCD(2, 526) = ( 2 x 526 ) / 526
= 2 / 526
= 2
Step3:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
So, Greatest Common Divisor of 344, 686, 526, 815 is 1
