HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 957, 87 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 957, 87 is 3 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 585, 957, 87 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 585, 957, 87 is 3.
HCF(585, 957, 87) = 3
HCF of 585, 957, 87 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 957, 87 is 3.
Highest Common Factor of 585,957,87 is 3
Step 1: Since 957 > 585, we apply the division lemma to 957 and 585, to get
957 = 585 x 1 + 372
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 372 and 585, to get
585 = 372 x 1 + 213
Step 3: We consider the new divisor 372 and the new remainder 213, and apply the division lemma to get
372 = 213 x 1 + 159
We consider the new divisor 213 and the new remainder 159,and apply the division lemma to get
213 = 159 x 1 + 54
We consider the new divisor 159 and the new remainder 54,and apply the division lemma to get
159 = 54 x 2 + 51
We consider the new divisor 54 and the new remainder 51,and apply the division lemma to get
54 = 51 x 1 + 3
We consider the new divisor 51 and the new remainder 3,and apply the division lemma to get
51 = 3 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 585 and 957 is 3
Notice that 3 = HCF(51,3) = HCF(54,51) = HCF(159,54) = HCF(213,159) = HCF(372,213) = HCF(585,372) = HCF(957,585) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 3, we apply the division lemma to 87 and 3, to get
87 = 3 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 87 is 3
Notice that 3 = HCF(87,3) .
