HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 765, 372, 769 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 765, 372, 769 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 765, 372, 769 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 765, 372, 769 is 1.
HCF(765, 372, 769) = 1
HCF of 765, 372, 769 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 765, 372, 769 is 1.
Highest Common Factor of 765,372,769 is 1
Step 1: Since 765 > 372, we apply the division lemma to 765 and 372, to get
765 = 372 x 2 + 21
Step 2: Since the reminder 372 ≠ 0, we apply division lemma to 21 and 372, to get
372 = 21 x 17 + 15
Step 3: We consider the new divisor 21 and the new remainder 15, and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 765 and 372 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(372,21) = HCF(765,372) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 769 > 3, we apply the division lemma to 769 and 3, to get
769 = 3 x 256 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 769 is 1
Notice that 1 = HCF(3,1) = HCF(769,3) .
