HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 23, 812, 690, 462 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 23, 812, 690, 462 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, 812, 690, 462 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, 812, 690, 462 is 1.
HCF(23, 812, 690, 462) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 23, 812, 690, 462 is 1.
Step 1: Since 812 > 23, we apply the division lemma to 812 and 23, to get
812 = 23 x 35 + 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 812 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(812,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 690 > 1, we apply the division lemma to 690 and 1, to get
690 = 1 x 690 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 690 is 1
Notice that 1 = HCF(690,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 462 > 1, we apply the division lemma to 462 and 1, to get
462 = 1 x 462 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 462 is 1
Notice that 1 = HCF(462,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
