HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 873, 278 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 873, 278 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 491, 873, 278 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 491, 873, 278 is 1.
HCF(491, 873, 278) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 491, 873, 278 is 1.
Step 1: Since 873 > 491, we apply the division lemma to 873 and 491, to get
873 = 491 x 1 + 382
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 382 and 491, to get
491 = 382 x 1 + 109
Step 3: We consider the new divisor 382 and the new remainder 109, and apply the division lemma to get
382 = 109 x 3 + 55
We consider the new divisor 109 and the new remainder 55,and apply the division lemma to get
109 = 55 x 1 + 54
We consider the new divisor 55 and the new remainder 54,and apply the division lemma to get
55 = 54 x 1 + 1
We consider the new divisor 54 and the new remainder 1,and apply the division lemma to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 873 is 1
Notice that 1 = HCF(54,1) = HCF(55,54) = HCF(109,55) = HCF(382,109) = HCF(491,382) = HCF(873,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 278 > 1, we apply the division lemma to 278 and 1, to get
278 = 1 x 278 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 278 is 1
Notice that 1 = HCF(278,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
