HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 75, 285, 609 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 75, 285, 609 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 75, 285, 609 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 75, 285, 609 is 3.
HCF(75, 285, 609) = 3
HCF of 75, 285, 609 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 75, 285, 609 is 3.
Highest Common Factor of 75,285,609 is 3
Step 1: Since 285 > 75, we apply the division lemma to 285 and 75, to get
285 = 75 x 3 + 60
Step 2: Since the reminder 75 ≠ 0, we apply division lemma to 60 and 75, to get
75 = 60 x 1 + 15
Step 3: We consider the new divisor 60 and the new remainder 15, and apply the division lemma to get
60 = 15 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 75 and 285 is 15
Notice that 15 = HCF(60,15) = HCF(75,60) = HCF(285,75) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 609 > 15, we apply the division lemma to 609 and 15, to get
609 = 15 x 40 + 9
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 9 and 15, to get
15 = 9 x 1 + 6
Step 3: 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 15 and 609 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(609,15) .
