HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 894, 490, 417 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 894, 490, 417 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 894, 490, 417 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 894, 490, 417 is 1.
HCF(894, 490, 417) = 1
HCF of 894, 490, 417 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 894, 490, 417 is 1.
Highest Common Factor of 894,490,417 is 1
Step 1: Since 894 > 490, we apply the division lemma to 894 and 490, to get
894 = 490 x 1 + 404
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 404 and 490, to get
490 = 404 x 1 + 86
Step 3: We consider the new divisor 404 and the new remainder 86, and apply the division lemma to get
404 = 86 x 4 + 60
We consider the new divisor 86 and the new remainder 60,and apply the division lemma to get
86 = 60 x 1 + 26
We consider the new divisor 60 and the new remainder 26,and apply the division lemma to get
60 = 26 x 2 + 8
We consider the new divisor 26 and the new remainder 8,and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 894 and 490 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(60,26) = HCF(86,60) = HCF(404,86) = HCF(490,404) = HCF(894,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 417 > 2, we apply the division lemma to 417 and 2, to get
417 = 2 x 208 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 417 is 1
Notice that 1 = HCF(2,1) = HCF(417,2) .
