HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 673, 946 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 417, 673, 946 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 417, 673, 946 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 417, 673, 946 is 1.
HCF(417, 673, 946) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 417, 673, 946 is 1.
Step 1: Since 673 > 417, we apply the division lemma to 673 and 417, to get
673 = 417 x 1 + 256
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 256 and 417, to get
417 = 256 x 1 + 161
Step 3: We consider the new divisor 256 and the new remainder 161, and apply the division lemma to get
256 = 161 x 1 + 95
We consider the new divisor 161 and the new remainder 95,and apply the division lemma to get
161 = 95 x 1 + 66
We consider the new divisor 95 and the new remainder 66,and apply the division lemma to get
95 = 66 x 1 + 29
We consider the new divisor 66 and the new remainder 29,and apply the division lemma to get
66 = 29 x 2 + 8
We consider the new divisor 29 and the new remainder 8,and apply the division lemma to get
29 = 8 x 3 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 417 and 673 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(29,8) = HCF(66,29) = HCF(95,66) = HCF(161,95) = HCF(256,161) = HCF(417,256) = HCF(673,417) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 946 > 1, we apply the division lemma to 946 and 1, to get
946 = 1 x 946 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 946 is 1
Notice that 1 = HCF(946,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
