Given numbers are 495, 401, 755, 647

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

Apply this formula for all numbers.

Step1:

LCM(495, 401) = 198495

GCD(495, 401) = ( 495 x 401 ) / 198495

= 495 / 401

= 495

Step2:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

Step3:

LCM(1, 647) = 647

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

= 1 / 647

= 1

So, Greatest Common Divisor of 495, 401, 755, 647 is 1
