Given numbers are 308, 685, 968, 480
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 685) = 210980
GCD(308, 685) = ( 308 x 685 ) / 210980
= 308 / 685
= 308
Step2:
LCM(1, 968) = 968
GCD(1, 968) = ( 1 x 968 ) / 968
= 1 / 968
= 1
Step3:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
So, Greatest Common Divisor of 308, 685, 968, 480 is 1
