Given numbers are 360, 655, 891, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(360, 655) = 47160
GCD(360, 655) = ( 360 x 655 ) / 47160
= 360 / 655
= 360
Step2:
LCM(5, 891) = 4455
GCD(5, 891) = ( 5 x 891 ) / 4455
= 5 / 891
= 5
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 360, 655, 891, 145 is 1
