HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 3149, 2499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 623, 3149, 2499 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 623, 3149, 2499 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 623, 3149, 2499 is 1.
HCF(623, 3149, 2499) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 623, 3149, 2499 is 1.
Step 1: Since 3149 > 623, we apply the division lemma to 3149 and 623, to get
3149 = 623 x 5 + 34
Step 2: Since the reminder 623 ≠ 0, we apply division lemma to 34 and 623, to get
623 = 34 x 18 + 11
Step 3: We consider the new divisor 34 and the new remainder 11, and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 623 and 3149 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(623,34) = HCF(3149,623) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2499 > 1, we apply the division lemma to 2499 and 1, to get
2499 = 1 x 2499 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2499 is 1
Notice that 1 = HCF(2499,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
