Given numbers are 465, 745, 987, 217

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

Apply this formula for all numbers.

Step1:

LCM(465, 745) = 69285

GCD(465, 745) = ( 465 x 745 ) / 69285

= 465 / 745

= 465

Step2:

LCM(5, 987) = 4935

GCD(5, 987) = ( 5 x 987 ) / 4935

= 5 / 987

= 5

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 465, 745, 987, 217 is 1
