GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 777) = 58275
GCD(225, 777) = ( 225 x 777 ) / 58275
= 225 / 777
= 225
Step2:
LCM(3, 770) = 2310
GCD(3, 770) = ( 3 x 770 ) / 2310
= 3 / 770
= 3
Step3:
LCM(1, 560) = 560
GCD(1, 560) = ( 1 x 560 ) / 560
= 1 / 560
= 1
So, Greatest Common Divisor of 225, 777, 770, 560 is 1
