Given numbers are 480, 542, 390, 863
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(480, 542) = 130080
GCD(480, 542) = ( 480 x 542 ) / 130080
= 480 / 542
= 480
Step2:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
Step3:
LCM(2, 863) = 1726
GCD(2, 863) = ( 2 x 863 ) / 1726
= 2 / 863
= 2
So, Greatest Common Divisor of 480, 542, 390, 863 is 1
