HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 343, 46 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 343, 46 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 434, 343, 46 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 434, 343, 46 is 1.
HCF(434, 343, 46) = 1
HCF of 434, 343, 46 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 434, 343, 46 is 1.
Highest Common Factor of 434,343,46 is 1
Step 1: Since 434 > 343, we apply the division lemma to 434 and 343, to get
434 = 343 x 1 + 91
Step 2: Since the reminder 343 ≠ 0, we apply division lemma to 91 and 343, to get
343 = 91 x 3 + 70
Step 3: We consider the new divisor 91 and the new remainder 70, and apply the division lemma to get
91 = 70 x 1 + 21
We consider the new divisor 70 and the new remainder 21,and apply the division lemma to get
70 = 21 x 3 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 434 and 343 is 7
Notice that 7 = HCF(21,7) = HCF(70,21) = HCF(91,70) = HCF(343,91) = HCF(434,343) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 46 > 7, we apply the division lemma to 46 and 7, to get
46 = 7 x 6 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 46 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(46,7) .
