Given numbers are 390, 862, 555, 879
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 862) = 168090
GCD(390, 862) = ( 390 x 862 ) / 168090
= 390 / 862
= 390
Step2:
LCM(2, 555) = 1110
GCD(2, 555) = ( 2 x 555 ) / 1110
= 2 / 555
= 2
Step3:
LCM(1, 879) = 879
GCD(1, 879) = ( 1 x 879 ) / 879
= 1 / 879
= 1
So, Greatest Common Divisor of 390, 862, 555, 879 is 1
