Given numbers are 345, 287, 987, 222

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

Apply this formula for all numbers.

Step1:

LCM(345, 287) = 99015

GCD(345, 287) = ( 345 x 287 ) / 99015

= 345 / 287

= 345

Step2:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 345, 287, 987, 222 is 1
