HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 229 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 229 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 390, 229 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 390, 229 is 1.
HCF(390, 229) = 1
HCF of 390, 229 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 229 is 1.
Highest Common Factor of 390,229 is 1
Step 1: Since 390 > 229, we apply the division lemma to 390 and 229, to get
390 = 229 x 1 + 161
Step 2: Since the reminder 229 ≠ 0, we apply division lemma to 161 and 229, to get
229 = 161 x 1 + 68
Step 3: We consider the new divisor 161 and the new remainder 68, and apply the division lemma to get
161 = 68 x 2 + 25
We consider the new divisor 68 and the new remainder 25,and apply the division lemma to get
68 = 25 x 2 + 18
We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get
25 = 18 x 1 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 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 390 and 229 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(68,25) = HCF(161,68) = HCF(229,161) = HCF(390,229) .
