HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 383, 690, 320 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 383, 690, 320 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 383, 690, 320 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 383, 690, 320 is 1.

HCF(383, 690, 320) = 1

HCF of 383, 690, 320 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 383, 690, 320 is 1.

Highest Common Factor of 383,690,320 using Euclid's algorithm

Highest Common Factor of 383,690,320 is 1

Step 1: Since 690 > 383, we apply the division lemma to 690 and 383, to get

690 = 383 x 1 + 307

Step 2: Since the reminder 383 ≠ 0, we apply division lemma to 307 and 383, to get

383 = 307 x 1 + 76

Step 3: We consider the new divisor 307 and the new remainder 76, and apply the division lemma to get

307 = 76 x 4 + 3

We consider the new divisor 76 and the new remainder 3,and apply the division lemma to get

76 = 3 x 25 + 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 383 and 690 is 1

Notice that 1 = HCF(3,1) = HCF(76,3) = HCF(307,76) = HCF(383,307) = HCF(690,383) .


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

Step 1: Since 320 > 1, we apply the division lemma to 320 and 1, to get

320 = 1 x 320 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 320 is 1

Notice that 1 = HCF(320,1) .
