HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 21894 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 419, 21894 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 419, 21894 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 419, 21894 is 1.
HCF(419, 21894) = 1
HCF of 419, 21894 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 419, 21894 is 1.
Highest Common Factor of 419,21894 is 1
Step 1: Since 21894 > 419, we apply the division lemma to 21894 and 419, to get
21894 = 419 x 52 + 106
Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 106 and 419, to get
419 = 106 x 3 + 101
Step 3: We consider the new divisor 106 and the new remainder 101, and apply the division lemma to get
106 = 101 x 1 + 5
We consider the new divisor 101 and the new remainder 5,and apply the division lemma to get
101 = 5 x 20 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 419 and 21894 is 1
Notice that 1 = HCF(5,1) = HCF(101,5) = HCF(106,101) = HCF(419,106) = HCF(21894,419) .
