HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 55, 75, 958 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 55, 75, 958 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 55, 75, 958 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 55, 75, 958 is 1.
HCF(55, 75, 958) = 1
HCF of 55, 75, 958 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 55, 75, 958 is 1.
Highest Common Factor of 55,75,958 is 1
Step 1: Since 75 > 55, we apply the division lemma to 75 and 55, to get
75 = 55 x 1 + 20
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 20 and 55, to get
55 = 20 x 2 + 15
Step 3: We consider the new divisor 20 and the new remainder 15, and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 55 and 75 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(55,20) = HCF(75,55) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 958 > 5, we apply the division lemma to 958 and 5, to get
958 = 5 x 191 + 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 958 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(958,5) .
