HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 766, 819, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 766, 819, 781 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 766, 819, 781 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 766, 819, 781 is 1.
HCF(766, 819, 781) = 1
HCF of 766, 819, 781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 766, 819, 781 is 1.
Highest Common Factor of 766,819,781 is 1
Step 1: Since 819 > 766, we apply the division lemma to 819 and 766, to get
819 = 766 x 1 + 53
Step 2: Since the reminder 766 ≠ 0, we apply division lemma to 53 and 766, to get
766 = 53 x 14 + 24
Step 3: We consider the new divisor 53 and the new remainder 24, and apply the division lemma to get
53 = 24 x 2 + 5
We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get
24 = 5 x 4 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 766 and 819 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(53,24) = HCF(766,53) = HCF(819,766) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get
781 = 1 x 781 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1
Notice that 1 = HCF(781,1) .
