HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 258, 653, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 258, 653, 973 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 258, 653, 973 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 258, 653, 973 is 1.
HCF(258, 653, 973) = 1
HCF of 258, 653, 973 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 258, 653, 973 is 1.
Highest Common Factor of 258,653,973 is 1
Step 1: Since 653 > 258, we apply the division lemma to 653 and 258, to get
653 = 258 x 2 + 137
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 137 and 258, to get
258 = 137 x 1 + 121
Step 3: We consider the new divisor 137 and the new remainder 121, and apply the division lemma to get
137 = 121 x 1 + 16
We consider the new divisor 121 and the new remainder 16,and apply the division lemma to get
121 = 16 x 7 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 258 and 653 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(121,16) = HCF(137,121) = HCF(258,137) = HCF(653,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 1, we apply the division lemma to 973 and 1, to get
973 = 1 x 973 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 973 is 1
Notice that 1 = HCF(973,1) .
