Given numbers are 845, 351, 440, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(845, 351) = 22815
GCD(845, 351) = ( 845 x 351 ) / 22815
= 845 / 351
= 845
Step2:
LCM(13, 440) = 5720
GCD(13, 440) = ( 13 x 440 ) / 5720
= 13 / 440
= 13
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 845, 351, 440, 153 is 1
