Given numbers are 178, 552, 647, 805

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

Apply this formula for all numbers.

Step1:

LCM(178, 552) = 49128

GCD(178, 552) = ( 178 x 552 ) / 49128

= 178 / 552

= 178

Step2:

LCM(2, 647) = 1294

GCD(2, 647) = ( 2 x 647 ) / 1294

= 2 / 647

= 2

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 178, 552, 647, 805 is 1
