HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 256 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 290, 256 is 2 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 290, 256 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 290, 256 is 2.

HCF(290, 256) = 2

HCF of 290, 256 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 290, 256 is 2.

Highest Common Factor of 290,256 using Euclid's algorithm

Highest Common Factor of 290,256 is 2

Step 1: Since 290 > 256, we apply the division lemma to 290 and 256, to get

290 = 256 x 1 + 34

Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 34 and 256, to get

256 = 34 x 7 + 18

Step 3: We consider the new divisor 34 and the new remainder 18, and apply the division lemma to get

34 = 18 x 1 + 16

We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get

18 = 16 x 1 + 2

We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get

16 = 2 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 290 and 256 is 2

Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(34,18) = HCF(256,34) = HCF(290,256) .
