HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 973, 601, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 973, 601, 117 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 973, 601, 117 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 973, 601, 117 is 1.
HCF(973, 601, 117) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 973, 601, 117 is 1.
Step 1: Since 973 > 601, we apply the division lemma to 973 and 601, to get
973 = 601 x 1 + 372
Step 2: Since the reminder 601 ≠ 0, we apply division lemma to 372 and 601, to get
601 = 372 x 1 + 229
Step 3: We consider the new divisor 372 and the new remainder 229, and apply the division lemma to get
372 = 229 x 1 + 143
We consider the new divisor 229 and the new remainder 143,and apply the division lemma to get
229 = 143 x 1 + 86
We consider the new divisor 143 and the new remainder 86,and apply the division lemma to get
143 = 86 x 1 + 57
We consider the new divisor 86 and the new remainder 57,and apply the division lemma to get
86 = 57 x 1 + 29
We consider the new divisor 57 and the new remainder 29,and apply the division lemma to get
57 = 29 x 1 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 973 and 601 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(57,29) = HCF(86,57) = HCF(143,86) = HCF(229,143) = HCF(372,229) = HCF(601,372) = HCF(973,601) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get
117 = 1 x 117 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1
Notice that 1 = HCF(117,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
