HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 325, 180, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 325, 180, 723 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 325, 180, 723 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 325, 180, 723 is 1.
HCF(325, 180, 723) = 1
HCF of 325, 180, 723 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 325, 180, 723 is 1.
Highest Common Factor of 325,180,723 is 1
Step 1: Since 325 > 180, we apply the division lemma to 325 and 180, to get
325 = 180 x 1 + 145
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 145 and 180, to get
180 = 145 x 1 + 35
Step 3: We consider the new divisor 145 and the new remainder 35, and apply the division lemma to get
145 = 35 x 4 + 5
We consider the new divisor 35 and the new remainder 5, and apply the division lemma to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 325 and 180 is 5
Notice that 5 = HCF(35,5) = HCF(145,35) = HCF(180,145) = HCF(325,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 723 > 5, we apply the division lemma to 723 and 5, to get
723 = 5 x 144 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 5 and 723 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(723,5) .
