HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 793, 491, 970 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 793, 491, 970 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 793, 491, 970 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 793, 491, 970 is 1.
HCF(793, 491, 970) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 793, 491, 970 is 1.
Step 1: Since 793 > 491, we apply the division lemma to 793 and 491, to get
793 = 491 x 1 + 302
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 302 and 491, to get
491 = 302 x 1 + 189
Step 3: We consider the new divisor 302 and the new remainder 189, and apply the division lemma to get
302 = 189 x 1 + 113
We consider the new divisor 189 and the new remainder 113,and apply the division lemma to get
189 = 113 x 1 + 76
We consider the new divisor 113 and the new remainder 76,and apply the division lemma to get
113 = 76 x 1 + 37
We consider the new divisor 76 and the new remainder 37,and apply the division lemma to get
76 = 37 x 2 + 2
We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get
37 = 2 x 18 + 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 793 and 491 is 1
Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(76,37) = HCF(113,76) = HCF(189,113) = HCF(302,189) = HCF(491,302) = HCF(793,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 970 > 1, we apply the division lemma to 970 and 1, to get
970 = 1 x 970 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 970 is 1
Notice that 1 = HCF(970,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
