Given numbers are 409, 670, 88, 861

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

Apply this formula for all numbers.

Step1:

LCM(409, 670) = 274030

GCD(409, 670) = ( 409 x 670 ) / 274030

= 409 / 670

= 409

Step2:

LCM(1, 88) = 88

GCD(1, 88) = ( 1 x 88 ) / 88

= 1 / 88

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 409, 670, 88, 861 is 1
