Given numbers are 518, 140, 821, 875
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(518, 140) = 5180
GCD(518, 140) = ( 518 x 140 ) / 5180
= 518 / 140
= 518
Step2:
LCM(14, 821) = 11494
GCD(14, 821) = ( 14 x 821 ) / 11494
= 14 / 821
= 14
Step3:
LCM(1, 875) = 875
GCD(1, 875) = ( 1 x 875 ) / 875
= 1 / 875
= 1
So, Greatest Common Divisor of 518, 140, 821, 875 is 1
