HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 130, 331, 982, 474 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 130, 331, 982, 474 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 130, 331, 982, 474 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 130, 331, 982, 474 is 1.
HCF(130, 331, 982, 474) = 1
HCF of 130, 331, 982, 474 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 130, 331, 982, 474 is 1.
Highest Common Factor of 130,331,982,474 is 1
Step 1: Since 331 > 130, we apply the division lemma to 331 and 130, to get
331 = 130 x 2 + 71
Step 2: Since the reminder 130 ≠ 0, we apply division lemma to 71 and 130, to get
130 = 71 x 1 + 59
Step 3: We consider the new divisor 71 and the new remainder 59, and apply the division lemma to get
71 = 59 x 1 + 12
We consider the new divisor 59 and the new remainder 12,and apply the division lemma to get
59 = 12 x 4 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 130 and 331 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(59,12) = HCF(71,59) = HCF(130,71) = HCF(331,130) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 982 > 1, we apply the division lemma to 982 and 1, to get
982 = 1 x 982 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 982 is 1
Notice that 1 = HCF(982,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 474 > 1, we apply the division lemma to 474 and 1, to get
474 = 1 x 474 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 474 is 1
Notice that 1 = HCF(474,1) .
