Given numbers are 408, 513, 689, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 513) = 69768
GCD(408, 513) = ( 408 x 513 ) / 69768
= 408 / 513
= 408
Step2:
LCM(3, 689) = 2067
GCD(3, 689) = ( 3 x 689 ) / 2067
= 3 / 689
= 3
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 408, 513, 689, 836 is 1
