HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 824, 419 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 664, 824, 419 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 664, 824, 419 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 664, 824, 419 is 1.

HCF(664, 824, 419) = 1

HCF of 664, 824, 419 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 664, 824, 419 is 1.

Highest Common Factor of 664,824,419 using Euclid's algorithm

Highest Common Factor of 664,824,419 is 1

Step 1: Since 824 > 664, we apply the division lemma to 824 and 664, to get

824 = 664 x 1 + 160

Step 2: Since the reminder 664 ≠ 0, we apply division lemma to 160 and 664, to get

664 = 160 x 4 + 24

Step 3: We consider the new divisor 160 and the new remainder 24, and apply the division lemma to get

160 = 24 x 6 + 16

We consider the new divisor 24 and the new remainder 16,and apply the division lemma to get

24 = 16 x 1 + 8

We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get

16 = 8 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 664 and 824 is 8

Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(160,24) = HCF(664,160) = HCF(824,664) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 419 > 8, we apply the division lemma to 419 and 8, to get

419 = 8 x 52 + 3

Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 3 and 8, to get

8 = 3 x 2 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 419 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(419,8) .
