Given numbers are 280, 580, 221, 834
The list of prime factors of all numbers are
Prime factors of 280 are 2 x 2 x 2 x 5 x 7
Prime factors of 580 are 2 x 2 x 5 x 29
Prime factors of 221 are 13 x 17
Prime factors of 834 are 2 x 3 x 139
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 280, 580, 221, 834
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 580) = 8120
GCD(280, 580) = ( 280 x 580 ) / 8120
= 280 / 580
= 280
Step2:
LCM(20, 221) = 4420
GCD(20, 221) = ( 20 x 221 ) / 4420
= 20 / 221
= 20
Step3:
LCM(1, 834) = 834
GCD(1, 834) = ( 1 x 834 ) / 834
= 1 / 834
= 1
So, Greatest Common Divisor of 280, 580, 221, 834 is 1
