Given numbers are 247, 304, 137, 830

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

Apply this formula for all numbers.

Step1:

LCM(247, 304) = 3952

GCD(247, 304) = ( 247 x 304 ) / 3952

= 247 / 304

= 247

Step2:

LCM(19, 137) = 2603

GCD(19, 137) = ( 19 x 137 ) / 2603

= 19 / 137

= 19

Step3:

LCM(1, 830) = 830

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

= 1 / 830

= 1

So, Greatest Common Divisor of 247, 304, 137, 830 is 1
