HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 6992, 2749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 275, 6992, 2749 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 275, 6992, 2749 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 275, 6992, 2749 is 1.
HCF(275, 6992, 2749) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 275, 6992, 2749 is 1.
Step 1: Since 6992 > 275, we apply the division lemma to 6992 and 275, to get
6992 = 275 x 25 + 117
Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 117 and 275, to get
275 = 117 x 2 + 41
Step 3: We consider the new divisor 117 and the new remainder 41, and apply the division lemma to get
117 = 41 x 2 + 35
We consider the new divisor 41 and the new remainder 35,and apply the division lemma to get
41 = 35 x 1 + 6
We consider the new divisor 35 and the new remainder 6,and apply the division lemma to get
35 = 6 x 5 + 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 275 and 6992 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(35,6) = HCF(41,35) = HCF(117,41) = HCF(275,117) = HCF(6992,275) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2749 > 1, we apply the division lemma to 2749 and 1, to get
2749 = 1 x 2749 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2749 is 1
Notice that 1 = HCF(2749,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
