Given numbers are 175, 645, 683, 987

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

Apply this formula for all numbers.

Step1:

LCM(175, 645) = 22575

GCD(175, 645) = ( 175 x 645 ) / 22575

= 175 / 645

= 175

Step2:

LCM(5, 683) = 3415

GCD(5, 683) = ( 5 x 683 ) / 3415

= 5 / 683

= 5

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 175, 645, 683, 987 is 1
