HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1405, 2715 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 1405, 2715 is 5 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 1405, 2715 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 1405, 2715 is 5.
HCF(1405, 2715) = 5
HCF of 1405, 2715 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1405, 2715 is 5.
Highest Common Factor of 1405,2715 is 5
Step 1: Since 2715 > 1405, we apply the division lemma to 2715 and 1405, to get
2715 = 1405 x 1 + 1310
Step 2: Since the reminder 1405 ≠ 0, we apply division lemma to 1310 and 1405, to get
1405 = 1310 x 1 + 95
Step 3: We consider the new divisor 1310 and the new remainder 95, and apply the division lemma to get
1310 = 95 x 13 + 75
We consider the new divisor 95 and the new remainder 75,and apply the division lemma to get
95 = 75 x 1 + 20
We consider the new divisor 75 and the new remainder 20,and apply the division lemma to get
75 = 20 x 3 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 1405 and 2715 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(75,20) = HCF(95,75) = HCF(1310,95) = HCF(1405,1310) = HCF(2715,1405) .
