Given numbers are 665, 314, 140, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 314) = 208810
GCD(665, 314) = ( 665 x 314 ) / 208810
= 665 / 314
= 665
Step2:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
Step3:
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
= 1 / 811
= 1
So, Greatest Common Divisor of 665, 314, 140, 811 is 1
