HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 46, 667, 815, 420 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 46, 667, 815, 420 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 46, 667, 815, 420 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 46, 667, 815, 420 is 1.
HCF(46, 667, 815, 420) = 1
HCF of 46, 667, 815, 420 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 46, 667, 815, 420 is 1.
Highest Common Factor of 46,667,815,420 is 1
Step 1: Since 667 > 46, we apply the division lemma to 667 and 46, to get
667 = 46 x 14 + 23
Step 2: Since the reminder 46 ≠ 0, we apply division lemma to 23 and 46, to get
46 = 23 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 46 and 667 is 23
Notice that 23 = HCF(46,23) = HCF(667,46) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 23, we apply the division lemma to 815 and 23, to get
815 = 23 x 35 + 10
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 10 and 23, to get
23 = 10 x 2 + 3
Step 3: We consider the new divisor 10 and the new remainder 3, and apply the division lemma to get
10 = 3 x 3 + 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 23 and 815 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(815,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 420 > 1, we apply the division lemma to 420 and 1, to get
420 = 1 x 420 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 420 is 1
Notice that 1 = HCF(420,1) .
