HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 627, 726 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 627, 726 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 791, 627, 726 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 791, 627, 726 is 1.
HCF(791, 627, 726) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 627, 726 is 1.
Step 1: Since 791 > 627, we apply the division lemma to 791 and 627, to get
791 = 627 x 1 + 164
Step 2: Since the reminder 627 ≠ 0, we apply division lemma to 164 and 627, to get
627 = 164 x 3 + 135
Step 3: We consider the new divisor 164 and the new remainder 135, and apply the division lemma to get
164 = 135 x 1 + 29
We consider the new divisor 135 and the new remainder 29,and apply the division lemma to get
135 = 29 x 4 + 19
We consider the new divisor 29 and the new remainder 19,and apply the division lemma to get
29 = 19 x 1 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 627 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(29,19) = HCF(135,29) = HCF(164,135) = HCF(627,164) = HCF(791,627) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 726 > 1, we apply the division lemma to 726 and 1, to get
726 = 1 x 726 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 726 is 1
Notice that 1 = HCF(726,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
