HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 316, 860, 345 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 68, 316, 860, 345 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 68, 316, 860, 345 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 68, 316, 860, 345 is 1.

HCF(68, 316, 860, 345) = 1

HCF of 68, 316, 860, 345 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 68, 316, 860, 345 is 1.

Highest Common Factor of 68,316,860,345 using Euclid's algorithm

Highest Common Factor of 68,316,860,345 is 1

Step 1: Since 316 > 68, we apply the division lemma to 316 and 68, to get

316 = 68 x 4 + 44

Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 44 and 68, to get

68 = 44 x 1 + 24

Step 3: We consider the new divisor 44 and the new remainder 24, and apply the division lemma to get

44 = 24 x 1 + 20

We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get

24 = 20 x 1 + 4

We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 68 and 316 is 4

Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(44,24) = HCF(68,44) = HCF(316,68) .


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

Step 1: Since 860 > 4, we apply the division lemma to 860 and 4, to get

860 = 4 x 215 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 860 is 4

Notice that 4 = HCF(860,4) .


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

Step 1: Since 345 > 4, we apply the division lemma to 345 and 4, to get

345 = 4 x 86 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 345 is 1

Notice that 1 = HCF(4,1) = HCF(345,4) .
