Given numbers are 208, 649, 263, 145

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

Apply this formula for all numbers.

Step1:

LCM(208, 649) = 134992

GCD(208, 649) = ( 208 x 649 ) / 134992

= 208 / 649

= 208

Step2:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 208, 649, 263, 145 is 1
