HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 267, 450, 987, 90 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 267, 450, 987, 90 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 267, 450, 987, 90 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 267, 450, 987, 90 is 3.
HCF(267, 450, 987, 90) = 3
HCF of 267, 450, 987, 90 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 267, 450, 987, 90 is 3.
Highest Common Factor of 267,450,987,90 is 3
Step 1: Since 450 > 267, we apply the division lemma to 450 and 267, to get
450 = 267 x 1 + 183
Step 2: Since the reminder 267 ≠ 0, we apply division lemma to 183 and 267, to get
267 = 183 x 1 + 84
Step 3: We consider the new divisor 183 and the new remainder 84, and apply the division lemma to get
183 = 84 x 2 + 15
We consider the new divisor 84 and the new remainder 15,and apply the division lemma to get
84 = 15 x 5 + 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 267 and 450 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(84,15) = HCF(183,84) = HCF(267,183) = HCF(450,267) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 987 > 3, we apply the division lemma to 987 and 3, to get
987 = 3 x 329 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 987 is 3
Notice that 3 = HCF(987,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 3, we apply the division lemma to 90 and 3, to get
90 = 3 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 90 is 3
Notice that 3 = HCF(90,3) .
