HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 182, 419 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 644, 182, 419 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 644, 182, 419 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 644, 182, 419 is 1.
HCF(644, 182, 419) = 1
HCF of 644, 182, 419 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 644, 182, 419 is 1.
Highest Common Factor of 644,182,419 is 1
Step 1: Since 644 > 182, we apply the division lemma to 644 and 182, to get
644 = 182 x 3 + 98
Step 2: Since the reminder 182 ≠ 0, we apply division lemma to 98 and 182, to get
182 = 98 x 1 + 84
Step 3: We consider the new divisor 98 and the new remainder 84, and apply the division lemma to get
98 = 84 x 1 + 14
We consider the new divisor 84 and the new remainder 14, and apply the division lemma to get
84 = 14 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 644 and 182 is 14
Notice that 14 = HCF(84,14) = HCF(98,84) = HCF(182,98) = HCF(644,182) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 419 > 14, we apply the division lemma to 419 and 14, to get
419 = 14 x 29 + 13
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 13 and 14, to get
14 = 13 x 1 + 1
Step 3: We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 419 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(419,14) .
