Given numbers are 861, 917, 413, 705

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

Apply this formula for all numbers.

Step1:

LCM(861, 917) = 112791

GCD(861, 917) = ( 861 x 917 ) / 112791

= 861 / 917

= 861

Step2:

LCM(7, 413) = 413

GCD(7, 413) = ( 7 x 413 ) / 413

= 7 / 413

= 7

Step3:

LCM(7, 705) = 4935

GCD(7, 705) = ( 7 x 705 ) / 4935

= 7 / 705

= 7

So, Greatest Common Divisor of 861, 917, 413, 705 is 1
