Given numbers are 108, 428, 655, 855
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(108, 428) = 11556
GCD(108, 428) = ( 108 x 428 ) / 11556
= 108 / 428
= 108
Step2:
LCM(4, 655) = 2620
GCD(4, 655) = ( 4 x 655 ) / 2620
= 4 / 655
= 4
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 108, 428, 655, 855 is 1
