HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 493 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 493 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 320, 493 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 320, 493 is 1.
HCF(320, 493) = 1
HCF of 320, 493 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 493 is 1.
Highest Common Factor of 320,493 is 1
Step 1: Since 493 > 320, we apply the division lemma to 493 and 320, to get
493 = 320 x 1 + 173
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 173 and 320, to get
320 = 173 x 1 + 147
Step 3: We consider the new divisor 173 and the new remainder 147, and apply the division lemma to get
173 = 147 x 1 + 26
We consider the new divisor 147 and the new remainder 26,and apply the division lemma to get
147 = 26 x 5 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 320 and 493 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(147,26) = HCF(173,147) = HCF(320,173) = HCF(493,320) .
