HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 987, 267 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 642, 987, 267 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 642, 987, 267 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 642, 987, 267 is 3.
HCF(642, 987, 267) = 3
HCF of 642, 987, 267 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 642, 987, 267 is 3.
Highest Common Factor of 642,987,267 is 3
Step 1: Since 987 > 642, we apply the division lemma to 987 and 642, to get
987 = 642 x 1 + 345
Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 345 and 642, to get
642 = 345 x 1 + 297
Step 3: We consider the new divisor 345 and the new remainder 297, and apply the division lemma to get
345 = 297 x 1 + 48
We consider the new divisor 297 and the new remainder 48,and apply the division lemma to get
297 = 48 x 6 + 9
We consider the new divisor 48 and the new remainder 9,and apply the division lemma to get
48 = 9 x 5 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 642 and 987 is 3
Notice that 3 = HCF(9,3) = HCF(48,9) = HCF(297,48) = HCF(345,297) = HCF(642,345) = HCF(987,642) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 267 > 3, we apply the division lemma to 267 and 3, to get
267 = 3 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 267 is 3
Notice that 3 = HCF(267,3) .
