Given numbers are 685, 672, 862, 480
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 672) = 460320
GCD(685, 672) = ( 685 x 672 ) / 460320
= 685 / 672
= 685
Step2:
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
= 1 / 862
= 1
Step3:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
So, Greatest Common Divisor of 685, 672, 862, 480 is 1
