HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 297 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 555, 297 is 3 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 555, 297 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 555, 297 is 3.
HCF(555, 297) = 3
HCF of 555, 297 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 555, 297 is 3.
Highest Common Factor of 555,297 is 3
Step 1: Since 555 > 297, we apply the division lemma to 555 and 297, to get
555 = 297 x 1 + 258
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 258 and 297, to get
297 = 258 x 1 + 39
Step 3: We consider the new divisor 258 and the new remainder 39, and apply the division lemma to get
258 = 39 x 6 + 24
We consider the new divisor 39 and the new remainder 24,and apply the division lemma to get
39 = 24 x 1 + 15
We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get
24 = 15 x 1 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 555 and 297 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(39,24) = HCF(258,39) = HCF(297,258) = HCF(555,297) .
