HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 675, 459, 99 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 675, 459, 99 is 9 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 675, 459, 99 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 675, 459, 99 is 9.
HCF(675, 459, 99) = 9
HCF of 675, 459, 99 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 675, 459, 99 is 9.
Highest Common Factor of 675,459,99 is 9
Step 1: Since 675 > 459, we apply the division lemma to 675 and 459, to get
675 = 459 x 1 + 216
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 216 and 459, to get
459 = 216 x 2 + 27
Step 3: We consider the new divisor 216 and the new remainder 27, and apply the division lemma to get
216 = 27 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 675 and 459 is 27
Notice that 27 = HCF(216,27) = HCF(459,216) = HCF(675,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99 > 27, we apply the division lemma to 99 and 27, to get
99 = 27 x 3 + 18
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 18 and 27, to get
27 = 18 x 1 + 9
Step 3: We consider the new divisor 18 and the new remainder 9, and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 27 and 99 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(99,27) .
