Given numbers are 455, 755, 647, 899

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

Apply this formula for all numbers.

Step1:

LCM(455, 755) = 68705

GCD(455, 755) = ( 455 x 755 ) / 68705

= 455 / 755

= 455

Step2:

LCM(5, 647) = 3235

GCD(5, 647) = ( 5 x 647 ) / 3235

= 5 / 647

= 5

Step3:

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

= 1 / 899

= 1

So, Greatest Common Divisor of 455, 755, 647, 899 is 1
