HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 618, 50 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 618, 50 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 905, 618, 50 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 905, 618, 50 is 1.
HCF(905, 618, 50) = 1
HCF of 905, 618, 50 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 905, 618, 50 is 1.
Highest Common Factor of 905,618,50 is 1
Step 1: Since 905 > 618, we apply the division lemma to 905 and 618, to get
905 = 618 x 1 + 287
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 287 and 618, to get
618 = 287 x 2 + 44
Step 3: We consider the new divisor 287 and the new remainder 44, and apply the division lemma to get
287 = 44 x 6 + 23
We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get
44 = 23 x 1 + 21
We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get
23 = 21 x 1 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 1
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 905 and 618 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(287,44) = HCF(618,287) = HCF(905,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 1, we apply the division lemma to 50 and 1, to get
50 = 1 x 50 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 50 is 1
Notice that 1 = HCF(50,1) .
