HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 645, 416, 967 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 645, 416, 967 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 645, 416, 967 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 645, 416, 967 is 1.

HCF(645, 416, 967) = 1

HCF of 645, 416, 967 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 645, 416, 967 is 1.

Highest Common Factor of 645,416,967 using Euclid's algorithm

Highest Common Factor of 645,416,967 is 1

Step 1: Since 645 > 416, we apply the division lemma to 645 and 416, to get

645 = 416 x 1 + 229

Step 2: Since the reminder 416 ≠ 0, we apply division lemma to 229 and 416, to get

416 = 229 x 1 + 187

Step 3: We consider the new divisor 229 and the new remainder 187, and apply the division lemma to get

229 = 187 x 1 + 42

We consider the new divisor 187 and the new remainder 42,and apply the division lemma to get

187 = 42 x 4 + 19

We consider the new divisor 42 and the new remainder 19,and apply the division lemma to get

42 = 19 x 2 + 4

We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get

19 = 4 x 4 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 645 and 416 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(42,19) = HCF(187,42) = HCF(229,187) = HCF(416,229) = HCF(645,416) .

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

Step 1: Since 967 > 1, we apply the division lemma to 967 and 1, to get

967 = 1 x 967 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 967 is 1

Notice that 1 = HCF(967,1) .
