HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 309, 851 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 309, 851 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 309, 851 is 1.
HCF(309, 851) = 1
HCF of 309, 851 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 309, 851 is 1.
Highest Common Factor of 309,851 is 1
Step 1: Since 851 > 309, we apply the division lemma to 851 and 309, to get
851 = 309 x 2 + 233
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 233 and 309, to get
309 = 233 x 1 + 76
Step 3: We consider the new divisor 233 and the new remainder 76, and apply the division lemma to get
233 = 76 x 3 + 5
We consider the new divisor 76 and the new remainder 5,and apply the division lemma to get
76 = 5 x 15 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 309 and 851 is 1
Notice that 1 = HCF(5,1) = HCF(76,5) = HCF(233,76) = HCF(309,233) = HCF(851,309) .
