HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 63, 291, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 63, 291, 49 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, 291, 49 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, 291, 49 is 1.
HCF(63, 291, 49) = 1
HCF of 63, 291, 49 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, 291, 49 is 1.
Highest Common Factor of 63,291,49 is 1
Step 1: Since 291 > 63, we apply the division lemma to 291 and 63, to get
291 = 63 x 4 + 39
Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 39 and 63, to get
63 = 39 x 1 + 24
Step 3: We consider the new divisor 39 and the new remainder 24, and apply the division lemma to get
39 = 24 x 1 + 15
We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get
24 = 15 x 1 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 63 and 291 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(39,24) = HCF(63,39) = HCF(291,63) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 3, we apply the division lemma to 49 and 3, to get
49 = 3 x 16 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 49 is 1
Notice that 1 = HCF(3,1) = HCF(49,3) .
