Given numbers are 830, 275, 639, 953

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

Apply this formula for all numbers.

Step1:

LCM(830, 275) = 45650

GCD(830, 275) = ( 830 x 275 ) / 45650

= 830 / 275

= 830

Step2:

LCM(5, 639) = 3195

GCD(5, 639) = ( 5 x 639 ) / 3195

= 5 / 639

= 5

Step3:

LCM(1, 953) = 953

GCD(1, 953) = ( 1 x 953 ) / 953

= 1 / 953

= 1

So, Greatest Common Divisor of 830, 275, 639, 953 is 1
