Given numbers are 506, 687, 705, 808
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(506, 687) = 347622
GCD(506, 687) = ( 506 x 687 ) / 347622
= 506 / 687
= 506
Step2:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
Step3:
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
= 1 / 808
= 1
So, Greatest Common Divisor of 506, 687, 705, 808 is 1
