HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 847, 161, 754, 17 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 847, 161, 754, 17 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 847, 161, 754, 17 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 847, 161, 754, 17 is 1.

HCF(847, 161, 754, 17) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 847, 161, 754, 17 is 1.

Highest Common Factor of 847,161,754,17 using Euclid's algorithm

Highest Common Factor of 847,161,754,17 is 1

Step 1: Since 847 > 161, we apply the division lemma to 847 and 161, to get

847 = 161 x 5 + 42

Step 2: Since the reminder 161 ≠ 0, we apply division lemma to 42 and 161, to get

161 = 42 x 3 + 35

Step 3: We consider the new divisor 42 and the new remainder 35, and apply the division lemma to get

42 = 35 x 1 + 7

We consider the new divisor 35 and the new remainder 7, and apply the division lemma to get

35 = 7 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 847 and 161 is 7

Notice that 7 = HCF(35,7) = HCF(42,35) = HCF(161,42) = HCF(847,161) .


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

Step 1: Since 754 > 7, we apply the division lemma to 754 and 7, to get

754 = 7 x 107 + 5

Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 5 and 7, to get

7 = 5 x 1 + 2

Step 3: 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 7 and 754 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(754,7) .


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

Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get

17 = 1 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1

Notice that 1 = HCF(17,1) .
