Given numbers are 553, 217, 821, 460

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

Apply this formula for all numbers.

Step1:

LCM(553, 217) = 17143

GCD(553, 217) = ( 553 x 217 ) / 17143

= 553 / 217

= 553

Step2:

LCM(7, 821) = 5747

GCD(7, 821) = ( 7 x 821 ) / 5747

= 7 / 821

= 7

Step3:

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

= 1 / 460

= 1

So, Greatest Common Divisor of 553, 217, 821, 460 is 1
