HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 925, 765 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 925, 765 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, 925, 765 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, 925, 765 is 1.
HCF(321, 925, 765) = 1
HCF of 321, 925, 765 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, 925, 765 is 1.
Highest Common Factor of 321,925,765 is 1
Step 1: Since 925 > 321, we apply the division lemma to 925 and 321, to get
925 = 321 x 2 + 283
Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 283 and 321, to get
321 = 283 x 1 + 38
Step 3: We consider the new divisor 283 and the new remainder 38, and apply the division lemma to get
283 = 38 x 7 + 17
We consider the new divisor 38 and the new remainder 17,and apply the division lemma to get
38 = 17 x 2 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 321 and 925 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(38,17) = HCF(283,38) = HCF(321,283) = HCF(925,321) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 765 > 1, we apply the division lemma to 765 and 1, to get
765 = 1 x 765 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 765 is 1
Notice that 1 = HCF(765,1) .
