HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 286, 424 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 286, 424 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 423, 286, 424 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 423, 286, 424 is 1.
HCF(423, 286, 424) = 1
HCF of 423, 286, 424 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 423, 286, 424 is 1.
Highest Common Factor of 423,286,424 is 1
Step 1: Since 423 > 286, we apply the division lemma to 423 and 286, to get
423 = 286 x 1 + 137
Step 2: Since the reminder 286 ≠ 0, we apply division lemma to 137 and 286, to get
286 = 137 x 2 + 12
Step 3: We consider the new divisor 137 and the new remainder 12, and apply the division lemma to get
137 = 12 x 11 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
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 423 and 286 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(137,12) = HCF(286,137) = HCF(423,286) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 424 > 1, we apply the division lemma to 424 and 1, to get
424 = 1 x 424 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 424 is 1
Notice that 1 = HCF(424,1) .
