Given numbers are 518, 390, 117, 804
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(518, 390) = 101010
GCD(518, 390) = ( 518 x 390 ) / 101010
= 518 / 390
= 518
Step2:
LCM(2, 117) = 234
GCD(2, 117) = ( 2 x 117 ) / 234
= 2 / 117
= 2
Step3:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
So, Greatest Common Divisor of 518, 390, 117, 804 is 1
