HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 800, 456, 68 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 800, 456, 68 is 4 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 800, 456, 68 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 800, 456, 68 is 4.

HCF(800, 456, 68) = 4

HCF of 800, 456, 68 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 800, 456, 68 is 4.

Highest Common Factor of 800,456,68 using Euclid's algorithm

Highest Common Factor of 800,456,68 is 4

Step 1: Since 800 > 456, we apply the division lemma to 800 and 456, to get

800 = 456 x 1 + 344

Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 344 and 456, to get

456 = 344 x 1 + 112

Step 3: We consider the new divisor 344 and the new remainder 112, and apply the division lemma to get

344 = 112 x 3 + 8

We consider the new divisor 112 and the new remainder 8, and apply the division lemma to get

112 = 8 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 800 and 456 is 8

Notice that 8 = HCF(112,8) = HCF(344,112) = HCF(456,344) = HCF(800,456) .


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

Step 1: Since 68 > 8, we apply the division lemma to 68 and 8, to get

68 = 8 x 8 + 4

Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 4 and 8, to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 8 and 68 is 4

Notice that 4 = HCF(8,4) = HCF(68,8) .
