HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 994, 97, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 994, 97, 723 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 268, 994, 97, 723 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 268, 994, 97, 723 is 1.
HCF(268, 994, 97, 723) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 268, 994, 97, 723 is 1.
Step 1: Since 994 > 268, we apply the division lemma to 994 and 268, to get
994 = 268 x 3 + 190
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 190 and 268, to get
268 = 190 x 1 + 78
Step 3: We consider the new divisor 190 and the new remainder 78, and apply the division lemma to get
190 = 78 x 2 + 34
We consider the new divisor 78 and the new remainder 34,and apply the division lemma to get
78 = 34 x 2 + 10
We consider the new divisor 34 and the new remainder 10,and apply the division lemma to get
34 = 10 x 3 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 268 and 994 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(34,10) = HCF(78,34) = HCF(190,78) = HCF(268,190) = HCF(994,268) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 97 > 2, we apply the division lemma to 97 and 2, to get
97 = 2 x 48 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 97 is 1
Notice that 1 = HCF(2,1) = HCF(97,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 723 > 1, we apply the division lemma to 723 and 1, to get
723 = 1 x 723 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 723 is 1
Notice that 1 = HCF(723,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
