Given numbers are 432, 680, 120, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 680) = 36720
GCD(432, 680) = ( 432 x 680 ) / 36720
= 432 / 680
= 432
Step2:
LCM(8, 120) = 120
GCD(8, 120) = ( 8 x 120 ) / 120
= 8 / 120
= 8
Step3:
LCM(8, 845) = 6760
GCD(8, 845) = ( 8 x 845 ) / 6760
= 8 / 845
= 8
So, Greatest Common Divisor of 432, 680, 120, 845 is 1
