Given numbers are 515, 480, 815, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 480) = 49440
GCD(515, 480) = ( 515 x 480 ) / 49440
= 515 / 480
= 515
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 129) = 645
GCD(5, 129) = ( 5 x 129 ) / 645
= 5 / 129
= 5
So, Greatest Common Divisor of 515, 480, 815, 129 is 1
