Given numbers are 123, 885, 851, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 885) = 36285
GCD(123, 885) = ( 123 x 885 ) / 36285
= 123 / 885
= 123
Step2:
LCM(3, 851) = 2553
GCD(3, 851) = ( 3 x 851 ) / 2553
= 3 / 851
= 3
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 123, 885, 851, 170 is 1
