HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 23, 30, 923, 863 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 23, 30, 923, 863 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 23, 30, 923, 863 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 23, 30, 923, 863 is 1.
HCF(23, 30, 923, 863) = 1
HCF of 23, 30, 923, 863 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 23, 30, 923, 863 is 1.
Highest Common Factor of 23,30,923,863 is 1
Step 1: Since 30 > 23, we apply the division lemma to 30 and 23, to get
30 = 23 x 1 + 7
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 7 and 23, to get
23 = 7 x 3 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 23 and 30 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(30,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 923 > 1, we apply the division lemma to 923 and 1, to get
923 = 1 x 923 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 923 is 1
Notice that 1 = HCF(923,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 863 > 1, we apply the division lemma to 863 and 1, to get
863 = 1 x 863 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1
Notice that 1 = HCF(863,1) .
