HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 455, 368 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 455, 368 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 455, 368 is 1.

HCF(455, 368) = 1

HCF of 455, 368 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 455, 368 is 1.

Highest Common Factor of 455,368 using Euclid's algorithm

Highest Common Factor of 455,368 is 1

Step 1: Since 455 > 368, we apply the division lemma to 455 and 368, to get

455 = 368 x 1 + 87

Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 87 and 368, to get

368 = 87 x 4 + 20

Step 3: We consider the new divisor 87 and the new remainder 20, and apply the division lemma to get

87 = 20 x 4 + 7

We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get

20 = 7 x 2 + 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 455 and 368 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(87,20) = HCF(368,87) = HCF(455,368) .
