Given numbers are 515, 140, 824, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 140) = 14420
GCD(515, 140) = ( 515 x 140 ) / 14420
= 515 / 140
= 515
Step2:
LCM(5, 824) = 4120
GCD(5, 824) = ( 5 x 824 ) / 4120
= 5 / 824
= 5
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 515, 140, 824, 687 is 1
