Given numbers are 355, 290, 649, 160

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

Apply this formula for all numbers.

Step1:

LCM(355, 290) = 20590

GCD(355, 290) = ( 355 x 290 ) / 20590

= 355 / 290

= 355

Step2:

LCM(5, 649) = 3245

GCD(5, 649) = ( 5 x 649 ) / 3245

= 5 / 649

= 5

Step3:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

So, Greatest Common Divisor of 355, 290, 649, 160 is 1
