HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 129, 458, 290 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 129, 458, 290 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, 458, 290 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, 458, 290 is 1.
HCF(129, 458, 290) = 1
HCF of 129, 458, 290 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 129, 458, 290 is 1.
Highest Common Factor of 129,458,290 is 1
Step 1: Since 458 > 129, we apply the division lemma to 458 and 129, to get
458 = 129 x 3 + 71
Step 2: Since the reminder 129 ≠ 0, we apply division lemma to 71 and 129, to get
129 = 71 x 1 + 58
Step 3: We consider the new divisor 71 and the new remainder 58, and apply the division lemma to get
71 = 58 x 1 + 13
We consider the new divisor 58 and the new remainder 13,and apply the division lemma to get
58 = 13 x 4 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 129 and 458 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(58,13) = HCF(71,58) = HCF(129,71) = HCF(458,129) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 290 > 1, we apply the division lemma to 290 and 1, to get
290 = 1 x 290 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 290 is 1
Notice that 1 = HCF(290,1) .
