HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 965, 874, 625 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 810, 965, 874, 625 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 810, 965, 874, 625 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 810, 965, 874, 625 is 1.

HCF(810, 965, 874, 625) = 1

Highest common factor (HCF) of 810, 965, 874, 625 is 1.

Highest Common Factor of 810,965,874,625 using Euclid's algorithm

Highest Common Factor of 810,965,874,625 is 1

Step 1: Since 965 > 810, we apply the division lemma to 965 and 810, to get

965 = 810 x 1 + 155

Step 2: Since the reminder 810 ≠ 0, we apply division lemma to 155 and 810, to get

810 = 155 x 5 + 35

Step 3: We consider the new divisor 155 and the new remainder 35, and apply the division lemma to get

155 = 35 x 4 + 15

We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get

35 = 15 x 2 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 810 and 965 is 5

Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(155,35) = HCF(810,155) = HCF(965,810) .

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

Step 1: Since 874 > 5, we apply the division lemma to 874 and 5, to get

874 = 5 x 174 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: 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 5 and 874 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(874,5) .

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

Step 1: Since 625 > 1, we apply the division lemma to 625 and 1, to get

625 = 1 x 625 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 625 is 1

Notice that 1 = HCF(625,1) .
