HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 244, 154 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 417, 244, 154 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, 244, 154 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, 244, 154 is 1.
HCF(417, 244, 154) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 417, 244, 154 is 1.
Step 1: Since 417 > 244, we apply the division lemma to 417 and 244, to get
417 = 244 x 1 + 173
Step 2: Since the reminder 244 ≠ 0, we apply division lemma to 173 and 244, to get
244 = 173 x 1 + 71
Step 3: We consider the new divisor 173 and the new remainder 71, and apply the division lemma to get
173 = 71 x 2 + 31
We consider the new divisor 71 and the new remainder 31,and apply the division lemma to get
71 = 31 x 2 + 9
We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get
31 = 9 x 3 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 417 and 244 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(71,31) = HCF(173,71) = HCF(244,173) = HCF(417,244) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 154 > 1, we apply the division lemma to 154 and 1, to get
154 = 1 x 154 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 154 is 1
Notice that 1 = HCF(154,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
