HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 98, 80, 14, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 98, 80, 14, 309 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 98, 80, 14, 309 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 98, 80, 14, 309 is 1.
HCF(98, 80, 14, 309) = 1
HCF of 98, 80, 14, 309 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 98, 80, 14, 309 is 1.
Highest Common Factor of 98,80,14,309 is 1
Step 1: Since 98 > 80, we apply the division lemma to 98 and 80, to get
98 = 80 x 1 + 18
Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 18 and 80, to get
80 = 18 x 4 + 8
Step 3: We consider the new divisor 18 and the new remainder 8, and apply the division lemma to get
18 = 8 x 2 + 2
We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 98 and 80 is 2
Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(80,18) = HCF(98,80) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 14 > 2, we apply the division lemma to 14 and 2, to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 14 is 2
Notice that 2 = HCF(14,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 309 > 2, we apply the division lemma to 309 and 2, to get
309 = 2 x 154 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 309 is 1
Notice that 1 = HCF(2,1) = HCF(309,2) .
