HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 633, 256, 815, 382 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 633, 256, 815, 382 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 633, 256, 815, 382 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 633, 256, 815, 382 is 1.
HCF(633, 256, 815, 382) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 633, 256, 815, 382 is 1.
Step 1: Since 633 > 256, we apply the division lemma to 633 and 256, to get
633 = 256 x 2 + 121
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 121 and 256, to get
256 = 121 x 2 + 14
Step 3: We consider the new divisor 121 and the new remainder 14, and apply the division lemma to get
121 = 14 x 8 + 9
We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get
14 = 9 x 1 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 633 and 256 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(121,14) = HCF(256,121) = HCF(633,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 1, we apply the division lemma to 815 and 1, to get
815 = 1 x 815 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 815 is 1
Notice that 1 = HCF(815,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 382 > 1, we apply the division lemma to 382 and 1, to get
382 = 1 x 382 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 382 is 1
Notice that 1 = HCF(382,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
