HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 927, 527, 468 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 927, 527, 468 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, 927, 527, 468 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, 927, 527, 468 is 1.
HCF(423, 927, 527, 468) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 423, 927, 527, 468 is 1.
Step 1: Since 927 > 423, we apply the division lemma to 927 and 423, to get
927 = 423 x 2 + 81
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 81 and 423, to get
423 = 81 x 5 + 18
Step 3: We consider the new divisor 81 and the new remainder 18, and apply the division lemma to get
81 = 18 x 4 + 9
We consider the new divisor 18 and the new remainder 9, and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 423 and 927 is 9
Notice that 9 = HCF(18,9) = HCF(81,18) = HCF(423,81) = HCF(927,423) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 527 > 9, we apply the division lemma to 527 and 9, to get
527 = 9 x 58 + 5
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 5 and 9, to get
9 = 5 x 1 + 4
Step 3: We consider the new divisor 5 and the new remainder 4, and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 527 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(527,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 1, we apply the division lemma to 468 and 1, to get
468 = 1 x 468 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 468 is 1
Notice that 1 = HCF(468,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
