HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 832, 142, 449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 832, 142, 449 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 832, 142, 449 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 832, 142, 449 is 1.
HCF(832, 142, 449) = 1
HCF of 832, 142, 449 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 832, 142, 449 is 1.
Highest Common Factor of 832,142,449 is 1
Step 1: Since 832 > 142, we apply the division lemma to 832 and 142, to get
832 = 142 x 5 + 122
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 122 and 142, to get
142 = 122 x 1 + 20
Step 3: We consider the new divisor 122 and the new remainder 20, and apply the division lemma to get
122 = 20 x 6 + 2
We consider the new divisor 20 and the new remainder 2, and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 832 and 142 is 2
Notice that 2 = HCF(20,2) = HCF(122,20) = HCF(142,122) = HCF(832,142) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 449 > 2, we apply the division lemma to 449 and 2, to get
449 = 2 x 224 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 449 is 1
Notice that 1 = HCF(2,1) = HCF(449,2) .
