Given numbers are 865, 419, 647, 757

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

Apply this formula for all numbers.

Step1:

LCM(865, 419) = 362435

GCD(865, 419) = ( 865 x 419 ) / 362435

= 865 / 419

= 865

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

So, Greatest Common Divisor of 865, 419, 647, 757 is 1
