HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 473, 4619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 473, 4619 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 473, 4619 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 473, 4619 is 1.

HCF(473, 4619) = 1

Highest Common Factor of 473,4619 using Euclid's algorithm

Highest Common Factor of 473,4619 is 1

Step 1: Since 4619 > 473, we apply the division lemma to 4619 and 473, to get

4619 = 473 x 9 + 362

Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 362 and 473, to get

473 = 362 x 1 + 111

Step 3: We consider the new divisor 362 and the new remainder 111, and apply the division lemma to get

362 = 111 x 3 + 29

We consider the new divisor 111 and the new remainder 29,and apply the division lemma to get

111 = 29 x 3 + 24

We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get

29 = 24 x 1 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 473 and 4619 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(111,29) = HCF(362,111) = HCF(473,362) = HCF(4619,473) .
