HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 129, 70924 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 129, 70924 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 129, 70924 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 129, 70924 is 1.
HCF(129, 70924) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 129, 70924 is 1.
Step 1: Since 70924 > 129, we apply the division lemma to 70924 and 129, to get
70924 = 129 x 549 + 103
Step 2: Since the reminder 129 ≠ 0, we apply division lemma to 103 and 129, to get
129 = 103 x 1 + 26
Step 3: We consider the new divisor 103 and the new remainder 26, and apply the division lemma to get
103 = 26 x 3 + 25
We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get
26 = 25 x 1 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 129 and 70924 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(103,26) = HCF(129,103) = HCF(70924,129) .
Here are some samples of HCF using Euclid's Algorithm calculations.
