Given numbers are 208, 864, 162, 647

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

Apply this formula for all numbers.

Step1:

LCM(208, 864) = 11232

GCD(208, 864) = ( 208 x 864 ) / 11232

= 208 / 864

= 208

Step2:

LCM(16, 162) = 1296

GCD(16, 162) = ( 16 x 162 ) / 1296

= 16 / 162

= 16

Step3:

LCM(2, 647) = 1294

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

= 2 / 647

= 2

So, Greatest Common Divisor of 208, 864, 162, 647 is 1
