HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 904, 399, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 904, 399, 422 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 904, 399, 422 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 904, 399, 422 is 1.
HCF(904, 399, 422) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 904, 399, 422 is 1.
Step 1: Since 904 > 399, we apply the division lemma to 904 and 399, to get
904 = 399 x 2 + 106
Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 106 and 399, to get
399 = 106 x 3 + 81
Step 3: We consider the new divisor 106 and the new remainder 81, and apply the division lemma to get
106 = 81 x 1 + 25
We consider the new divisor 81 and the new remainder 25,and apply the division lemma to get
81 = 25 x 3 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 904 and 399 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(81,25) = HCF(106,81) = HCF(399,106) = HCF(904,399) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 422 > 1, we apply the division lemma to 422 and 1, to get
422 = 1 x 422 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 422 is 1
Notice that 1 = HCF(422,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
