HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 897, 258, 557 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 897, 258, 557 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 897, 258, 557 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 897, 258, 557 is 1.
HCF(897, 258, 557) = 1
HCF of 897, 258, 557 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 897, 258, 557 is 1.
Highest Common Factor of 897,258,557 is 1
Step 1: Since 897 > 258, we apply the division lemma to 897 and 258, to get
897 = 258 x 3 + 123
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 123 and 258, to get
258 = 123 x 2 + 12
Step 3: We consider the new divisor 123 and the new remainder 12, and apply the division lemma to get
123 = 12 x 10 + 3
We consider the new divisor 12 and the new remainder 3, and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 897 and 258 is 3
Notice that 3 = HCF(12,3) = HCF(123,12) = HCF(258,123) = HCF(897,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 557 > 3, we apply the division lemma to 557 and 3, to get
557 = 3 x 185 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 557 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(557,3) .
