Given numbers are 218, 649, 162, 555

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

Apply this formula for all numbers.

Step1:

LCM(218, 649) = 141482

GCD(218, 649) = ( 218 x 649 ) / 141482

= 218 / 649

= 218

Step2:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 218, 649, 162, 555 is 1
