HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 775, 172 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 679, 775, 172 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 679, 775, 172 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 679, 775, 172 is 1.

HCF(679, 775, 172) = 1

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

HCF of:

Highest common factor (HCF) of 679, 775, 172 is 1.

Highest Common Factor of 679,775,172 using Euclid's algorithm

Highest Common Factor of 679,775,172 is 1

Step 1: Since 775 > 679, we apply the division lemma to 775 and 679, to get

775 = 679 x 1 + 96

Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 96 and 679, to get

679 = 96 x 7 + 7

Step 3: We consider the new divisor 96 and the new remainder 7, and apply the division lemma to get

96 = 7 x 13 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 679 and 775 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(96,7) = HCF(679,96) = HCF(775,679) .

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

Step 1: Since 172 > 1, we apply the division lemma to 172 and 1, to get

172 = 1 x 172 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 172 is 1

Notice that 1 = HCF(172,1) .
