HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 341, 978, 772 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 341, 978, 772 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 341, 978, 772 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 341, 978, 772 is 1.
HCF(341, 978, 772) = 1
HCF of 341, 978, 772 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 341, 978, 772 is 1.
Highest Common Factor of 341,978,772 is 1
Step 1: Since 978 > 341, we apply the division lemma to 978 and 341, to get
978 = 341 x 2 + 296
Step 2: Since the reminder 341 ≠ 0, we apply division lemma to 296 and 341, to get
341 = 296 x 1 + 45
Step 3: We consider the new divisor 296 and the new remainder 45, and apply the division lemma to get
296 = 45 x 6 + 26
We consider the new divisor 45 and the new remainder 26,and apply the division lemma to get
45 = 26 x 1 + 19
We consider the new divisor 26 and the new remainder 19,and apply the division lemma to get
26 = 19 x 1 + 7
We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get
19 = 7 x 2 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 341 and 978 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(26,19) = HCF(45,26) = HCF(296,45) = HCF(341,296) = HCF(978,341) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 772 > 1, we apply the division lemma to 772 and 1, to get
772 = 1 x 772 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 772 is 1
Notice that 1 = HCF(772,1) .
