HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 520, 670 i.e. 10 the largest integer that leaves a remainder zero for all numbers.

HCF of 920, 520, 670 is 10 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 920, 520, 670 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 920, 520, 670 is 10.

HCF(920, 520, 670) = 10

## HCF of 920, 520, 670 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 920, 520, 670 is 10. ### Highest Common Factor of 920,520,670 is 10

Step 1: Since 920 > 520, we apply the division lemma to 920 and 520, to get

920 = 520 x 1 + 400

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 400 and 520, to get

520 = 400 x 1 + 120

Step 3: We consider the new divisor 400 and the new remainder 120, and apply the division lemma to get

400 = 120 x 3 + 40

We consider the new divisor 120 and the new remainder 40, and apply the division lemma to get

120 = 40 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 920 and 520 is 40

Notice that 40 = HCF(120,40) = HCF(400,120) = HCF(520,400) = HCF(920,520) .

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

Step 1: Since 670 > 40, we apply the division lemma to 670 and 40, to get

670 = 40 x 16 + 30

Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 30 and 40, to get

40 = 30 x 1 + 10

Step 3: We consider the new divisor 30 and the new remainder 10, and apply the division lemma to get

30 = 10 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 40 and 670 is 10

Notice that 10 = HCF(30,10) = HCF(40,30) = HCF(670,40) .
