HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 457, 841, 878 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 457, 841, 878 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 457, 841, 878 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 457, 841, 878 is 1.

HCF(457, 841, 878) = 1

HCF of 457, 841, 878 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 457, 841, 878 is 1.

Highest Common Factor of 457,841,878 using Euclid's algorithm

Highest Common Factor of 457,841,878 is 1

Step 1: Since 841 > 457, we apply the division lemma to 841 and 457, to get

841 = 457 x 1 + 384

Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 384 and 457, to get

457 = 384 x 1 + 73

Step 3: We consider the new divisor 384 and the new remainder 73, and apply the division lemma to get

384 = 73 x 5 + 19

We consider the new divisor 73 and the new remainder 19,and apply the division lemma to get

73 = 19 x 3 + 16

We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get

19 = 16 x 1 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 457 and 841 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(73,19) = HCF(384,73) = HCF(457,384) = HCF(841,457) .

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

Step 1: Since 878 > 1, we apply the division lemma to 878 and 1, to get

878 = 1 x 878 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 878 is 1

Notice that 1 = HCF(878,1) .
