Given numbers are 604, 428, 255, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(604, 428) = 64628
GCD(604, 428) = ( 604 x 428 ) / 64628
= 604 / 428
= 604
Step2:
LCM(4, 255) = 1020
GCD(4, 255) = ( 4 x 255 ) / 1020
= 4 / 255
= 4
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 604, 428, 255, 147 is 1
