Given numbers are 480, 578, 280, 878
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(480, 578) = 138720
GCD(480, 578) = ( 480 x 578 ) / 138720
= 480 / 578
= 480
Step2:
LCM(2, 280) = 280
GCD(2, 280) = ( 2 x 280 ) / 280
= 2 / 280
= 2
Step3:
LCM(2, 878) = 878
GCD(2, 878) = ( 2 x 878 ) / 878
= 2 / 878
= 2
So, Greatest Common Divisor of 480, 578, 280, 878 is 2
