HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 49, 58, 129, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 49, 58, 129, 631 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 49, 58, 129, 631 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 49, 58, 129, 631 is 1.
HCF(49, 58, 129, 631) = 1
HCF of 49, 58, 129, 631 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 49, 58, 129, 631 is 1.
Highest Common Factor of 49,58,129,631 is 1
Step 1: Since 58 > 49, we apply the division lemma to 58 and 49, to get
58 = 49 x 1 + 9
Step 2: Since the reminder 49 ≠ 0, we apply division lemma to 9 and 49, to get
49 = 9 x 5 + 4
Step 3: We consider the new divisor 9 and the new remainder 4, and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 49 and 58 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(49,9) = HCF(58,49) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 129 > 1, we apply the division lemma to 129 and 1, to get
129 = 1 x 129 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 129 is 1
Notice that 1 = HCF(129,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 631 > 1, we apply the division lemma to 631 and 1, to get
631 = 1 x 631 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 631 is 1
Notice that 1 = HCF(631,1) .
