HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 855, 914 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 285, 855, 914 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 285, 855, 914 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 285, 855, 914 is 1.
HCF(285, 855, 914) = 1
HCF of 285, 855, 914 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 285, 855, 914 is 1.
Highest Common Factor of 285,855,914 is 1
Step 1: Since 855 > 285, we apply the division lemma to 855 and 285, to get
855 = 285 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 285, the HCF of 285 and 855 is 285
Notice that 285 = HCF(855,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 914 > 285, we apply the division lemma to 914 and 285, to get
914 = 285 x 3 + 59
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 59 and 285, to get
285 = 59 x 4 + 49
Step 3: We consider the new divisor 59 and the new remainder 49, and apply the division lemma to get
59 = 49 x 1 + 10
We consider the new divisor 49 and the new remainder 10,and apply the division lemma to get
49 = 10 x 4 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 285 and 914 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(49,10) = HCF(59,49) = HCF(285,59) = HCF(914,285) .
