HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 355, 891 is 1 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 355, 891 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 355, 891 is 1.

HCF(355, 891) = 1

HCF of 355, 891 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 355, 891 is 1.

Highest Common Factor of 355,891 using Euclid's algorithm

Highest Common Factor of 355,891 is 1

Step 1: Since 891 > 355, we apply the division lemma to 891 and 355, to get

891 = 355 x 2 + 181

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 181 and 355, to get

355 = 181 x 1 + 174

Step 3: We consider the new divisor 181 and the new remainder 174, and apply the division lemma to get

181 = 174 x 1 + 7

We consider the new divisor 174 and the new remainder 7,and apply the division lemma to get

174 = 7 x 24 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 355 and 891 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(174,7) = HCF(181,174) = HCF(355,181) = HCF(891,355) .
