HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 63, 644, 519 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 63, 644, 519 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 63, 644, 519 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 63, 644, 519 is 1.
HCF(63, 644, 519) = 1
HCF of 63, 644, 519 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 63, 644, 519 is 1.
Highest Common Factor of 63,644,519 is 1
Step 1: Since 644 > 63, we apply the division lemma to 644 and 63, to get
644 = 63 x 10 + 14
Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 14 and 63, to get
63 = 14 x 4 + 7
Step 3: We consider the new divisor 14 and the new remainder 7, and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 63 and 644 is 7
Notice that 7 = HCF(14,7) = HCF(63,14) = HCF(644,63) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 519 > 7, we apply the division lemma to 519 and 7, to get
519 = 7 x 74 + 1
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 1 and 7, to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 519 is 1
Notice that 1 = HCF(7,1) = HCF(519,7) .
