HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 878, 617, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 878, 617, 57 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 878, 617, 57 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 878, 617, 57 is 1.
HCF(878, 617, 57) = 1
HCF of 878, 617, 57 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 878, 617, 57 is 1.
Highest Common Factor of 878,617,57 is 1
Step 1: Since 878 > 617, we apply the division lemma to 878 and 617, to get
878 = 617 x 1 + 261
Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 261 and 617, to get
617 = 261 x 2 + 95
Step 3: We consider the new divisor 261 and the new remainder 95, and apply the division lemma to get
261 = 95 x 2 + 71
We consider the new divisor 95 and the new remainder 71,and apply the division lemma to get
95 = 71 x 1 + 24
We consider the new divisor 71 and the new remainder 24,and apply the division lemma to get
71 = 24 x 2 + 23
We consider the new divisor 24 and the new remainder 23,and apply the division lemma to get
24 = 23 x 1 + 1
We consider the new divisor 23 and the new remainder 1,and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 878 and 617 is 1
Notice that 1 = HCF(23,1) = HCF(24,23) = HCF(71,24) = HCF(95,71) = HCF(261,95) = HCF(617,261) = HCF(878,617) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1
Notice that 1 = HCF(57,1) .
