HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 999, 806, 962 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 999, 806, 962 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 999, 806, 962 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 999, 806, 962 is 1.
HCF(999, 806, 962) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 999, 806, 962 is 1.
Step 1: Since 999 > 806, we apply the division lemma to 999 and 806, to get
999 = 806 x 1 + 193
Step 2: Since the reminder 806 ≠ 0, we apply division lemma to 193 and 806, to get
806 = 193 x 4 + 34
Step 3: We consider the new divisor 193 and the new remainder 34, and apply the division lemma to get
193 = 34 x 5 + 23
We consider the new divisor 34 and the new remainder 23,and apply the division lemma to get
34 = 23 x 1 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 999 and 806 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(193,34) = HCF(806,193) = HCF(999,806) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 962 > 1, we apply the division lemma to 962 and 1, to get
962 = 1 x 962 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 962 is 1
Notice that 1 = HCF(962,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
