HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 420, 449, 467 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 420, 449, 467 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 420, 449, 467 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 420, 449, 467 is 1.
HCF(420, 449, 467) = 1
HCF of 420, 449, 467 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 420, 449, 467 is 1.
Highest Common Factor of 420,449,467 is 1
Step 1: Since 449 > 420, we apply the division lemma to 449 and 420, to get
449 = 420 x 1 + 29
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 29 and 420, to get
420 = 29 x 14 + 14
Step 3: We consider the new divisor 29 and the new remainder 14, and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 420 and 449 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(420,29) = HCF(449,420) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 467 > 1, we apply the division lemma to 467 and 1, to get
467 = 1 x 467 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 467 is 1
Notice that 1 = HCF(467,1) .
