HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 848, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 848, 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 242, 848, 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 242, 848, 309 is 1.
HCF(242, 848, 309) = 1
HCF of 242, 848, 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 242, 848, 309 is 1.
Highest Common Factor of 242,848,309 is 1
Step 1: Since 848 > 242, we apply the division lemma to 848 and 242, to get
848 = 242 x 3 + 122
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 122 and 242, to get
242 = 122 x 1 + 120
Step 3: We consider the new divisor 122 and the new remainder 120, and apply the division lemma to get
122 = 120 x 1 + 2
We consider the new divisor 120 and the new remainder 2, and apply the division lemma to get
120 = 2 x 60 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 242 and 848 is 2
Notice that 2 = HCF(120,2) = HCF(122,120) = HCF(242,122) = HCF(848,242) .
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) .
