HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 417, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 150, 417, 287 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 150, 417, 287 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 150, 417, 287 is 1.
HCF(150, 417, 287) = 1
HCF of 150, 417, 287 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 150, 417, 287 is 1.
Highest Common Factor of 150,417,287 is 1
Step 1: Since 417 > 150, we apply the division lemma to 417 and 150, to get
417 = 150 x 2 + 117
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 117 and 150, to get
150 = 117 x 1 + 33
Step 3: We consider the new divisor 117 and the new remainder 33, and apply the division lemma to get
117 = 33 x 3 + 18
We consider the new divisor 33 and the new remainder 18,and apply the division lemma to get
33 = 18 x 1 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 150 and 417 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(33,18) = HCF(117,33) = HCF(150,117) = HCF(417,150) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 287 > 3, we apply the division lemma to 287 and 3, to get
287 = 3 x 95 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 287 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(287,3) .
