HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 115, 951, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 115, 951, 657 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 115, 951, 657 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 115, 951, 657 is 1.
HCF(115, 951, 657) = 1
HCF of 115, 951, 657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 115, 951, 657 is 1.
Highest Common Factor of 115,951,657 is 1
Step 1: Since 951 > 115, we apply the division lemma to 951 and 115, to get
951 = 115 x 8 + 31
Step 2: Since the reminder 115 ≠ 0, we apply division lemma to 31 and 115, to get
115 = 31 x 3 + 22
Step 3: We consider the new divisor 31 and the new remainder 22, and apply the division lemma to get
31 = 22 x 1 + 9
We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get
22 = 9 x 2 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 115 and 951 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(31,22) = HCF(115,31) = HCF(951,115) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 1, we apply the division lemma to 657 and 1, to get
657 = 1 x 657 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 657 is 1
Notice that 1 = HCF(657,1) .
