HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 631, 843, 567, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 631, 843, 567, 78 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 631, 843, 567, 78 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 631, 843, 567, 78 is 1.
HCF(631, 843, 567, 78) = 1
HCF of 631, 843, 567, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 631, 843, 567, 78 is 1.
Highest Common Factor of 631,843,567,78 is 1
Step 1: Since 843 > 631, we apply the division lemma to 843 and 631, to get
843 = 631 x 1 + 212
Step 2: Since the reminder 631 ≠ 0, we apply division lemma to 212 and 631, to get
631 = 212 x 2 + 207
Step 3: We consider the new divisor 212 and the new remainder 207, and apply the division lemma to get
212 = 207 x 1 + 5
We consider the new divisor 207 and the new remainder 5,and apply the division lemma to get
207 = 5 x 41 + 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 631 and 843 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(207,5) = HCF(212,207) = HCF(631,212) = HCF(843,631) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 567 > 1, we apply the division lemma to 567 and 1, to get
567 = 1 x 567 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 567 is 1
Notice that 1 = HCF(567,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
