Given numbers are 855, 247, 434, 830

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

Apply this formula for all numbers.

Step1:

LCM(855, 247) = 11115

GCD(855, 247) = ( 855 x 247 ) / 11115

= 855 / 247

= 855

Step2:

LCM(19, 434) = 8246

GCD(19, 434) = ( 19 x 434 ) / 8246

= 19 / 434

= 19

Step3:

LCM(1, 830) = 830

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

= 1 / 830

= 1

So, Greatest Common Divisor of 855, 247, 434, 830 is 1
