HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 964, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 369, 964, 191 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 369, 964, 191 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 369, 964, 191 is 1.
HCF(369, 964, 191) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 369, 964, 191 is 1.
Step 1: Since 964 > 369, we apply the division lemma to 964 and 369, to get
964 = 369 x 2 + 226
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 226 and 369, to get
369 = 226 x 1 + 143
Step 3: We consider the new divisor 226 and the new remainder 143, and apply the division lemma to get
226 = 143 x 1 + 83
We consider the new divisor 143 and the new remainder 83,and apply the division lemma to get
143 = 83 x 1 + 60
We consider the new divisor 83 and the new remainder 60,and apply the division lemma to get
83 = 60 x 1 + 23
We consider the new divisor 60 and the new remainder 23,and apply the division lemma to get
60 = 23 x 2 + 14
We consider the new divisor 23 and the new remainder 14,and apply the division lemma to get
23 = 14 x 1 + 9
We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get
14 = 9 x 1 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma 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 369 and 964 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(23,14) = HCF(60,23) = HCF(83,60) = HCF(143,83) = HCF(226,143) = HCF(369,226) = HCF(964,369) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 191 > 1, we apply the division lemma to 191 and 1, to get
191 = 1 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 191 is 1
Notice that 1 = HCF(191,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
