Given numbers are 830, 397, 801, 663

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

Apply this formula for all numbers.

Step1:

LCM(830, 397) = 329510

GCD(830, 397) = ( 830 x 397 ) / 329510

= 830 / 397

= 830

Step2:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 830, 397, 801, 663 is 1
