GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(495, 288) = 15840
GCD(495, 288) = ( 495 x 288 ) / 15840
= 495 / 288
= 495
Step2:
LCM(9, 858) = 2574
GCD(9, 858) = ( 9 x 858 ) / 2574
= 9 / 858
= 9
Step3:
LCM(3, 455) = 1365
GCD(3, 455) = ( 3 x 455 ) / 1365
= 3 / 455
= 3
So, Greatest Common Divisor of 495, 288, 858, 455 is 1
