HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 348, 771, 170, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 348, 771, 170, 31 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 348, 771, 170, 31 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 348, 771, 170, 31 is 1.
HCF(348, 771, 170, 31) = 1
HCF of 348, 771, 170, 31 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 348, 771, 170, 31 is 1.
Highest Common Factor of 348,771,170,31 is 1
Step 1: Since 771 > 348, we apply the division lemma to 771 and 348, to get
771 = 348 x 2 + 75
Step 2: Since the reminder 348 ≠ 0, we apply division lemma to 75 and 348, to get
348 = 75 x 4 + 48
Step 3: We consider the new divisor 75 and the new remainder 48, and apply the division lemma to get
75 = 48 x 1 + 27
We consider the new divisor 48 and the new remainder 27,and apply the division lemma to get
48 = 27 x 1 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 348 and 771 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(48,27) = HCF(75,48) = HCF(348,75) = HCF(771,348) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 170 > 3, we apply the division lemma to 170 and 3, to get
170 = 3 x 56 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 170 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(170,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 1, we apply the division lemma to 31 and 1, to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31 is 1
Notice that 1 = HCF(31,1) .
