Given numbers are 647, 864, 973, 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, 864) = 559008

GCD(647, 864) = ( 647 x 864 ) / 559008

= 647 / 864

= 647

Step2:

LCM(1, 973) = 973

GCD(1, 973) = ( 1 x 973 ) / 973

= 1 / 973

= 1

Step3:

LCM(1, 830) = 830

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

= 1 / 830

= 1

So, Greatest Common Divisor of 647, 864, 973, 830 is 1
