HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 152, 409 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 152, 409 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 152, 409 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 152, 409 is 1.
HCF(152, 409) = 1
HCF of 152, 409 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 152, 409 is 1.
Highest Common Factor of 152,409 is 1
Step 1: Since 409 > 152, we apply the division lemma to 409 and 152, to get
409 = 152 x 2 + 105
Step 2: Since the reminder 152 ≠ 0, we apply division lemma to 105 and 152, to get
152 = 105 x 1 + 47
Step 3: We consider the new divisor 105 and the new remainder 47, and apply the division lemma to get
105 = 47 x 2 + 11
We consider the new divisor 47 and the new remainder 11,and apply the division lemma to get
47 = 11 x 4 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 152 and 409 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(47,11) = HCF(105,47) = HCF(152,105) = HCF(409,152) .
