Given numbers are 647, 991, 733, 830

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

Apply this formula for all numbers.

Step1:

LCM(647, 991) = 641177

GCD(647, 991) = ( 647 x 991 ) / 641177

= 647 / 991

= 647

Step2:

LCM(1, 733) = 733

GCD(1, 733) = ( 1 x 733 ) / 733

= 1 / 733

= 1

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 647, 991, 733, 830 is 1
