HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 335, 978, 659 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 450, 335, 978, 659 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 450, 335, 978, 659 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 450, 335, 978, 659 is 1.
HCF(450, 335, 978, 659) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 450, 335, 978, 659 is 1.
Step 1: Since 450 > 335, we apply the division lemma to 450 and 335, to get
450 = 335 x 1 + 115
Step 2: Since the reminder 335 ≠ 0, we apply division lemma to 115 and 335, to get
335 = 115 x 2 + 105
Step 3: We consider the new divisor 115 and the new remainder 105, and apply the division lemma to get
115 = 105 x 1 + 10
We consider the new divisor 105 and the new remainder 10,and apply the division lemma to get
105 = 10 x 10 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 450 and 335 is 5
Notice that 5 = HCF(10,5) = HCF(105,10) = HCF(115,105) = HCF(335,115) = HCF(450,335) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 978 > 5, we apply the division lemma to 978 and 5, to get
978 = 5 x 195 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: 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 5 and 978 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(978,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 659 > 1, we apply the division lemma to 659 and 1, to get
659 = 1 x 659 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 659 is 1
Notice that 1 = HCF(659,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
