HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 790 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 321, 790 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 321, 790 is 1.
HCF(321, 790) = 1
HCF of 321, 790 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 321, 790 is 1.
Highest Common Factor of 321,790 is 1
Step 1: Since 790 > 321, we apply the division lemma to 790 and 321, to get
790 = 321 x 2 + 148
Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 148 and 321, to get
321 = 148 x 2 + 25
Step 3: We consider the new divisor 148 and the new remainder 25, and apply the division lemma to get
148 = 25 x 5 + 23
We consider the new divisor 25 and the new remainder 23,and apply the division lemma to get
25 = 23 x 1 + 2
We consider the new divisor 23 and the new remainder 2,and apply the division lemma to get
23 = 2 x 11 + 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 321 and 790 is 1
Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(25,23) = HCF(148,25) = HCF(321,148) = HCF(790,321) .
