HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 927, 723, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 927, 723, 49 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 927, 723, 49 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 927, 723, 49 is 1.
HCF(927, 723, 49) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 927, 723, 49 is 1.
Step 1: Since 927 > 723, we apply the division lemma to 927 and 723, to get
927 = 723 x 1 + 204
Step 2: Since the reminder 723 ≠ 0, we apply division lemma to 204 and 723, to get
723 = 204 x 3 + 111
Step 3: We consider the new divisor 204 and the new remainder 111, and apply the division lemma to get
204 = 111 x 1 + 93
We consider the new divisor 111 and the new remainder 93,and apply the division lemma to get
111 = 93 x 1 + 18
We consider the new divisor 93 and the new remainder 18,and apply the division lemma to get
93 = 18 x 5 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 927 and 723 is 3
Notice that 3 = HCF(18,3) = HCF(93,18) = HCF(111,93) = HCF(204,111) = HCF(723,204) = HCF(927,723) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 3, we apply the division lemma to 49 and 3, to get
49 = 3 x 16 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 49 is 1
Notice that 1 = HCF(3,1) = HCF(49,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
