HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 769, 563, 732 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 769, 563, 732 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 769, 563, 732 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 769, 563, 732 is 1.
HCF(769, 563, 732) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 769, 563, 732 is 1.
Step 1: Since 769 > 563, we apply the division lemma to 769 and 563, to get
769 = 563 x 1 + 206
Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 206 and 563, to get
563 = 206 x 2 + 151
Step 3: We consider the new divisor 206 and the new remainder 151, and apply the division lemma to get
206 = 151 x 1 + 55
We consider the new divisor 151 and the new remainder 55,and apply the division lemma to get
151 = 55 x 2 + 41
We consider the new divisor 55 and the new remainder 41,and apply the division lemma to get
55 = 41 x 1 + 14
We consider the new divisor 41 and the new remainder 14,and apply the division lemma to get
41 = 14 x 2 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 769 and 563 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(41,14) = HCF(55,41) = HCF(151,55) = HCF(206,151) = HCF(563,206) = HCF(769,563) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 732 > 1, we apply the division lemma to 732 and 1, to get
732 = 1 x 732 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 732 is 1
Notice that 1 = HCF(732,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
