HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 329, 193, 573 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 329, 193, 573 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 329, 193, 573 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 329, 193, 573 is 1.
HCF(329, 193, 573) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 329, 193, 573 is 1.
Step 1: Since 329 > 193, we apply the division lemma to 329 and 193, to get
329 = 193 x 1 + 136
Step 2: Since the reminder 193 ≠ 0, we apply division lemma to 136 and 193, to get
193 = 136 x 1 + 57
Step 3: We consider the new divisor 136 and the new remainder 57, and apply the division lemma to get
136 = 57 x 2 + 22
We consider the new divisor 57 and the new remainder 22,and apply the division lemma to get
57 = 22 x 2 + 13
We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get
22 = 13 x 1 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 329 and 193 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(57,22) = HCF(136,57) = HCF(193,136) = HCF(329,193) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 1, we apply the division lemma to 573 and 1, to get
573 = 1 x 573 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 573 is 1
Notice that 1 = HCF(573,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
