HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 631, 524, 318 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 423, 631, 524, 318 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, 631, 524, 318 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, 631, 524, 318 is 1.
HCF(423, 631, 524, 318) = 1
HCF of 423, 631, 524, 318 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, 631, 524, 318 is 1.
Highest Common Factor of 423,631,524,318 is 1
Step 1: Since 631 > 423, we apply the division lemma to 631 and 423, to get
631 = 423 x 1 + 208
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 208 and 423, to get
423 = 208 x 2 + 7
Step 3: We consider the new divisor 208 and the new remainder 7, and apply the division lemma to get
208 = 7 x 29 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 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 631 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(208,7) = HCF(423,208) = HCF(631,423) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 524 > 1, we apply the division lemma to 524 and 1, to get
524 = 1 x 524 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 524 is 1
Notice that 1 = HCF(524,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 318 > 1, we apply the division lemma to 318 and 1, to get
318 = 1 x 318 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1
Notice that 1 = HCF(318,1) .
