HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 31, 27, 86, 980 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 31, 27, 86, 980 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 31, 27, 86, 980 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 31, 27, 86, 980 is 1.
HCF(31, 27, 86, 980) = 1
HCF of 31, 27, 86, 980 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 31, 27, 86, 980 is 1.
Highest Common Factor of 31,27,86,980 is 1
Step 1: Since 31 > 27, we apply the division lemma to 31 and 27, to get
31 = 27 x 1 + 4
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 4 and 27, to get
27 = 4 x 6 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 31 and 27 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 980 > 1, we apply the division lemma to 980 and 1, to get
980 = 1 x 980 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 980 is 1
Notice that 1 = HCF(980,1) .
