HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 34, 359 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 34, 359 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 68, 34, 359 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 68, 34, 359 is 1.
HCF(68, 34, 359) = 1
HCF of 68, 34, 359 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 34, 359 is 1.
Highest Common Factor of 68,34,359 is 1
Step 1: Since 68 > 34, we apply the division lemma to 68 and 34, to get
68 = 34 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 68 and 34 is 34
Notice that 34 = HCF(68,34) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 359 > 34, we apply the division lemma to 359 and 34, to get
359 = 34 x 10 + 19
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 19 and 34, to get
34 = 19 x 1 + 15
Step 3: We consider the new divisor 19 and the new remainder 15, and apply the division lemma to get
19 = 15 x 1 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 34 and 359 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(34,19) = HCF(359,34) .
