HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2278, 2642, 25588 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 2278, 2642, 25588 is 2 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 2278, 2642, 25588 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 2278, 2642, 25588 is 2.
HCF(2278, 2642, 25588) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2278, 2642, 25588 is 2.
Step 1: Since 2642 > 2278, we apply the division lemma to 2642 and 2278, to get
2642 = 2278 x 1 + 364
Step 2: Since the reminder 2278 ≠ 0, we apply division lemma to 364 and 2278, to get
2278 = 364 x 6 + 94
Step 3: We consider the new divisor 364 and the new remainder 94, and apply the division lemma to get
364 = 94 x 3 + 82
We consider the new divisor 94 and the new remainder 82,and apply the division lemma to get
94 = 82 x 1 + 12
We consider the new divisor 82 and the new remainder 12,and apply the division lemma to get
82 = 12 x 6 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2278 and 2642 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(82,12) = HCF(94,82) = HCF(364,94) = HCF(2278,364) = HCF(2642,2278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25588 > 2, we apply the division lemma to 25588 and 2, to get
25588 = 2 x 12794 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 25588 is 2
Notice that 2 = HCF(25588,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
