HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 960, 552, 398 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 960, 552, 398 is 2 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 960, 552, 398 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 960, 552, 398 is 2.
HCF(960, 552, 398) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 960, 552, 398 is 2.
Step 1: Since 960 > 552, we apply the division lemma to 960 and 552, to get
960 = 552 x 1 + 408
Step 2: Since the reminder 552 ≠ 0, we apply division lemma to 408 and 552, to get
552 = 408 x 1 + 144
Step 3: We consider the new divisor 408 and the new remainder 144, and apply the division lemma to get
408 = 144 x 2 + 120
We consider the new divisor 144 and the new remainder 120,and apply the division lemma to get
144 = 120 x 1 + 24
We consider the new divisor 120 and the new remainder 24,and apply the division lemma to get
120 = 24 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 960 and 552 is 24
Notice that 24 = HCF(120,24) = HCF(144,120) = HCF(408,144) = HCF(552,408) = HCF(960,552) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 24, we apply the division lemma to 398 and 24, to get
398 = 24 x 16 + 14
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 14 and 24, to get
24 = 14 x 1 + 10
Step 3: We consider the new divisor 14 and the new remainder 10, and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 24 and 398 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(24,14) = HCF(398,24) .
Here are some samples of HCF using Euclid's Algorithm calculations.
