Given numbers are 480, 618, 905, 838
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(480, 618) = 49440
GCD(480, 618) = ( 480 x 618 ) / 49440
= 480 / 618
= 480
Step2:
LCM(6, 905) = 5430
GCD(6, 905) = ( 6 x 905 ) / 5430
= 6 / 905
= 6
Step3:
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
= 1 / 838
= 1
So, Greatest Common Divisor of 480, 618, 905, 838 is 1
