Given numbers are 845, 390, 879, 169
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(845, 390) = 5070
GCD(845, 390) = ( 845 x 390 ) / 5070
= 845 / 390
= 845
Step2:
LCM(65, 879) = 57135
GCD(65, 879) = ( 65 x 879 ) / 57135
= 65 / 879
= 65
Step3:
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
= 1 / 169
= 1
So, Greatest Common Divisor of 845, 390, 879, 169 is 1
