HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 825, 511, 223 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 825, 511, 223 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 297, 825, 511, 223 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 297, 825, 511, 223 is 1.
HCF(297, 825, 511, 223) = 1
HCF of 297, 825, 511, 223 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 825, 511, 223 is 1.
Highest Common Factor of 297,825,511,223 is 1
Step 1: Since 825 > 297, we apply the division lemma to 825 and 297, to get
825 = 297 x 2 + 231
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 231 and 297, to get
297 = 231 x 1 + 66
Step 3: We consider the new divisor 231 and the new remainder 66, and apply the division lemma to get
231 = 66 x 3 + 33
We consider the new divisor 66 and the new remainder 33, and apply the division lemma to get
66 = 33 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 297 and 825 is 33
Notice that 33 = HCF(66,33) = HCF(231,66) = HCF(297,231) = HCF(825,297) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 511 > 33, we apply the division lemma to 511 and 33, to get
511 = 33 x 15 + 16
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 16 and 33, to get
33 = 16 x 2 + 1
Step 3: We consider the new divisor 16 and the new remainder 1, and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 33 and 511 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(511,33) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 223 > 1, we apply the division lemma to 223 and 1, to get
223 = 1 x 223 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 223 is 1
Notice that 1 = HCF(223,1) .
