HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 175, 30838 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 175, 30838 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 175, 30838 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 175, 30838 is 1.
HCF(175, 30838) = 1
HCF of 175, 30838 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 175, 30838 is 1.
Highest Common Factor of 175,30838 is 1
Step 1: Since 30838 > 175, we apply the division lemma to 30838 and 175, to get
30838 = 175 x 176 + 38
Step 2: Since the reminder 175 ≠ 0, we apply division lemma to 38 and 175, to get
175 = 38 x 4 + 23
Step 3: We consider the new divisor 38 and the new remainder 23, and apply the division lemma to get
38 = 23 x 1 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 175 and 30838 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(38,23) = HCF(175,38) = HCF(30838,175) .
