HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 435, 806 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 84, 435, 806 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, 435, 806 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, 435, 806 is 1.
HCF(84, 435, 806) = 1
HCF of 84, 435, 806 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 84, 435, 806 is 1.
Highest Common Factor of 84,435,806 is 1
Step 1: Since 435 > 84, we apply the division lemma to 435 and 84, to get
435 = 84 x 5 + 15
Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 15 and 84, to get
84 = 15 x 5 + 9
Step 3: We consider the new divisor 15 and the new remainder 9, and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 84 and 435 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(84,15) = HCF(435,84) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 806 > 3, we apply the division lemma to 806 and 3, to get
806 = 3 x 268 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 806 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(806,3) .
