HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 342, 143, 804 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 84, 342, 143, 804 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 84, 342, 143, 804 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 84, 342, 143, 804 is 1.

HCF(84, 342, 143, 804) = 1

HCF of 84, 342, 143, 804 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 84, 342, 143, 804 is 1.

Highest Common Factor of 84,342,143,804 using Euclid's algorithm

Highest Common Factor of 84,342,143,804 is 1

Step 1: Since 342 > 84, we apply the division lemma to 342 and 84, to get

342 = 84 x 4 + 6

Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 6 and 84, to get

84 = 6 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 84 and 342 is 6

Notice that 6 = HCF(84,6) = HCF(342,84) .


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

Step 1: Since 143 > 6, we apply the division lemma to 143 and 6, to get

143 = 6 x 23 + 5

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get

6 = 5 x 1 + 1

Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 143 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(143,6) .


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

Step 1: Since 804 > 1, we apply the division lemma to 804 and 1, to get

804 = 1 x 804 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 804 is 1

Notice that 1 = HCF(804,1) .
