HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2618, 8515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2618, 8515 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 2618, 8515 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 2618, 8515 is 1.
HCF(2618, 8515) = 1
HCF of 2618, 8515 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2618, 8515 is 1.
Highest Common Factor of 2618,8515 is 1
Step 1: Since 8515 > 2618, we apply the division lemma to 8515 and 2618, to get
8515 = 2618 x 3 + 661
Step 2: Since the reminder 2618 ≠ 0, we apply division lemma to 661 and 2618, to get
2618 = 661 x 3 + 635
Step 3: We consider the new divisor 661 and the new remainder 635, and apply the division lemma to get
661 = 635 x 1 + 26
We consider the new divisor 635 and the new remainder 26,and apply the division lemma to get
635 = 26 x 24 + 11
We consider the new divisor 26 and the new remainder 11,and apply the division lemma to get
26 = 11 x 2 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 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 2618 and 8515 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(26,11) = HCF(635,26) = HCF(661,635) = HCF(2618,661) = HCF(8515,2618) .
