Given numbers are 485, 470, 557, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 470) = 45590
GCD(485, 470) = ( 485 x 470 ) / 45590
= 485 / 470
= 485
Step2:
LCM(5, 557) = 2785
GCD(5, 557) = ( 5 x 557 ) / 2785
= 5 / 557
= 5
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 485, 470, 557, 655 is 1
