HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 828, 898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 449, 828, 898 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 449, 828, 898 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 449, 828, 898 is 1.

HCF(449, 828, 898) = 1

Highest common factor (HCF) of 449, 828, 898 is 1.

Highest Common Factor of 449,828,898 using Euclid's algorithm

Highest Common Factor of 449,828,898 is 1

Step 1: Since 828 > 449, we apply the division lemma to 828 and 449, to get

828 = 449 x 1 + 379

Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 379 and 449, to get

449 = 379 x 1 + 70

Step 3: We consider the new divisor 379 and the new remainder 70, and apply the division lemma to get

379 = 70 x 5 + 29

We consider the new divisor 70 and the new remainder 29,and apply the division lemma to get

70 = 29 x 2 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 449 and 828 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(70,29) = HCF(379,70) = HCF(449,379) = HCF(828,449) .

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

Step 1: Since 898 > 1, we apply the division lemma to 898 and 1, to get

898 = 1 x 898 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 898 is 1

Notice that 1 = HCF(898,1) .
