HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 679, 450 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 891, 679, 450 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 891, 679, 450 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 891, 679, 450 is 1.

HCF(891, 679, 450) = 1

HCF of 891, 679, 450 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 891, 679, 450 is 1.

Highest Common Factor of 891,679,450 using Euclid's algorithm

Highest Common Factor of 891,679,450 is 1

Step 1: Since 891 > 679, we apply the division lemma to 891 and 679, to get

891 = 679 x 1 + 212

Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 212 and 679, to get

679 = 212 x 3 + 43

Step 3: We consider the new divisor 212 and the new remainder 43, and apply the division lemma to get

212 = 43 x 4 + 40

We consider the new divisor 43 and the new remainder 40,and apply the division lemma to get

43 = 40 x 1 + 3

We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get

40 = 3 x 13 + 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 891 and 679 is 1

Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(43,40) = HCF(212,43) = HCF(679,212) = HCF(891,679) .

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

Step 1: Since 450 > 1, we apply the division lemma to 450 and 1, to get

450 = 1 x 450 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 450 is 1

Notice that 1 = HCF(450,1) .
