Given numbers are 405, 781, 895, 277

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

Apply this formula for all numbers.

Step1:

LCM(405, 781) = 316305

GCD(405, 781) = ( 405 x 781 ) / 316305

= 405 / 781

= 405

Step2:

LCM(1, 895) = 895

GCD(1, 895) = ( 1 x 895 ) / 895

= 1 / 895

= 1

Step3:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1

So, Greatest Common Divisor of 405, 781, 895, 277 is 1
