HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 109, 808, 486 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 109, 808, 486 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 109, 808, 486 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 109, 808, 486 is 1.
HCF(109, 808, 486) = 1
HCF of 109, 808, 486 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 109, 808, 486 is 1.
Highest Common Factor of 109,808,486 is 1
Step 1: Since 808 > 109, we apply the division lemma to 808 and 109, to get
808 = 109 x 7 + 45
Step 2: Since the reminder 109 ≠ 0, we apply division lemma to 45 and 109, to get
109 = 45 x 2 + 19
Step 3: We consider the new divisor 45 and the new remainder 19, and apply the division lemma to get
45 = 19 x 2 + 7
We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get
19 = 7 x 2 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 109 and 808 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(45,19) = HCF(109,45) = HCF(808,109) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 486 > 1, we apply the division lemma to 486 and 1, to get
486 = 1 x 486 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 486 is 1
Notice that 1 = HCF(486,1) .
