HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 760, 790, 397 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 760, 790, 397 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 760, 790, 397 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 760, 790, 397 is 1.
HCF(760, 790, 397) = 1
HCF of 760, 790, 397 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 760, 790, 397 is 1.
Highest Common Factor of 760,790,397 is 1
Step 1: Since 790 > 760, we apply the division lemma to 790 and 760, to get
790 = 760 x 1 + 30
Step 2: Since the reminder 760 ≠ 0, we apply division lemma to 30 and 760, to get
760 = 30 x 25 + 10
Step 3: We consider the new divisor 30 and the new remainder 10, and apply the division lemma to get
30 = 10 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 760 and 790 is 10
Notice that 10 = HCF(30,10) = HCF(760,30) = HCF(790,760) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 397 > 10, we apply the division lemma to 397 and 10, to get
397 = 10 x 39 + 7
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 7 and 10, to get
10 = 7 x 1 + 3
Step 3: We consider the new divisor 7 and the new remainder 3, and apply the division lemma to get
7 = 3 x 2 + 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 10 and 397 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(397,10) .
