HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 58, 212, 987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 58, 212, 987 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 58, 212, 987 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 58, 212, 987 is 1.
HCF(58, 212, 987) = 1
HCF of 58, 212, 987 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 58, 212, 987 is 1.
Highest Common Factor of 58,212,987 is 1
Step 1: Since 212 > 58, we apply the division lemma to 212 and 58, to get
212 = 58 x 3 + 38
Step 2: Since the reminder 58 ≠ 0, we apply division lemma to 38 and 58, to get
58 = 38 x 1 + 20
Step 3: We consider the new divisor 38 and the new remainder 20, and apply the division lemma to get
38 = 20 x 1 + 18
We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get
20 = 18 x 1 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 58 and 212 is 2
Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(38,20) = HCF(58,38) = HCF(212,58) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 987 > 2, we apply the division lemma to 987 and 2, to get
987 = 2 x 493 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 987 is 1
Notice that 1 = HCF(2,1) = HCF(987,2) .
