Given numbers are 490, 488, 845, 143

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(490, 488) = 119560

GCD(490, 488) = ( 490 x 488 ) / 119560

= 490 / 488

= 490

Step2:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

Step3:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

So, Greatest Common Divisor of 490, 488, 845, 143 is 1
