HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 996, 742 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 996, 742 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 787, 996, 742 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 787, 996, 742 is 1.
HCF(787, 996, 742) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 996, 742 is 1.
Step 1: Since 996 > 787, we apply the division lemma to 996 and 787, to get
996 = 787 x 1 + 209
Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 209 and 787, to get
787 = 209 x 3 + 160
Step 3: We consider the new divisor 209 and the new remainder 160, and apply the division lemma to get
209 = 160 x 1 + 49
We consider the new divisor 160 and the new remainder 49,and apply the division lemma to get
160 = 49 x 3 + 13
We consider the new divisor 49 and the new remainder 13,and apply the division lemma to get
49 = 13 x 3 + 10
We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 996 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(49,13) = HCF(160,49) = HCF(209,160) = HCF(787,209) = HCF(996,787) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 742 > 1, we apply the division lemma to 742 and 1, to get
742 = 1 x 742 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 742 is 1
Notice that 1 = HCF(742,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
