HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 349, 274 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 626, 349, 274 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 626, 349, 274 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 626, 349, 274 is 1.
HCF(626, 349, 274) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 626, 349, 274 is 1.
Step 1: Since 626 > 349, we apply the division lemma to 626 and 349, to get
626 = 349 x 1 + 277
Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 277 and 349, to get
349 = 277 x 1 + 72
Step 3: We consider the new divisor 277 and the new remainder 72, and apply the division lemma to get
277 = 72 x 3 + 61
We consider the new divisor 72 and the new remainder 61,and apply the division lemma to get
72 = 61 x 1 + 11
We consider the new divisor 61 and the new remainder 11,and apply the division lemma to get
61 = 11 x 5 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 626 and 349 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(61,11) = HCF(72,61) = HCF(277,72) = HCF(349,277) = HCF(626,349) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 274 > 1, we apply the division lemma to 274 and 1, to get
274 = 1 x 274 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 274 is 1
Notice that 1 = HCF(274,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
