Given numbers are 143, 249, 647, 887

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

Apply this formula for all numbers.

Step1:

LCM(143, 249) = 35607

GCD(143, 249) = ( 143 x 249 ) / 35607

= 143 / 249

= 143

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 143, 249, 647, 887 is 1
