HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 38, 823, 505, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 38, 823, 505, 909 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 38, 823, 505, 909 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 38, 823, 505, 909 is 1.
HCF(38, 823, 505, 909) = 1
HCF of 38, 823, 505, 909 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 38, 823, 505, 909 is 1.
Highest Common Factor of 38,823,505,909 is 1
Step 1: Since 823 > 38, we apply the division lemma to 823 and 38, to get
823 = 38 x 21 + 25
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 25 and 38, to get
38 = 25 x 1 + 13
Step 3: We consider the new divisor 25 and the new remainder 13, and apply the division lemma to get
25 = 13 x 1 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 38 and 823 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(38,25) = HCF(823,38) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 1, we apply the division lemma to 505 and 1, to get
505 = 1 x 505 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 505 is 1
Notice that 1 = HCF(505,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 1, we apply the division lemma to 909 and 1, to get
909 = 1 x 909 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 909 is 1
Notice that 1 = HCF(909,1) .
