HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 57, 437, 258 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 57, 437, 258 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 57, 437, 258 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 57, 437, 258 is 1.
HCF(57, 437, 258) = 1
HCF of 57, 437, 258 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 57, 437, 258 is 1.
Highest Common Factor of 57,437,258 is 1
Step 1: Since 437 > 57, we apply the division lemma to 437 and 57, to get
437 = 57 x 7 + 38
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 38 and 57, to get
57 = 38 x 1 + 19
Step 3: We consider the new divisor 38 and the new remainder 19, and apply the division lemma to get
38 = 19 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 57 and 437 is 19
Notice that 19 = HCF(38,19) = HCF(57,38) = HCF(437,57) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 258 > 19, we apply the division lemma to 258 and 19, to get
258 = 19 x 13 + 11
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 11 and 19, to get
19 = 11 x 1 + 8
Step 3: We consider the new divisor 11 and the new remainder 8, and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
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 19 and 258 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(258,19) .
