HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 927, 988 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 927, 988 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 515, 927, 988 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 515, 927, 988 is 1.
HCF(515, 927, 988) = 1
HCF of 515, 927, 988 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 927, 988 is 1.
Highest Common Factor of 515,927,988 is 1
Step 1: Since 927 > 515, we apply the division lemma to 927 and 515, to get
927 = 515 x 1 + 412
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 412 and 515, to get
515 = 412 x 1 + 103
Step 3: We consider the new divisor 412 and the new remainder 103, and apply the division lemma to get
412 = 103 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 103, the HCF of 515 and 927 is 103
Notice that 103 = HCF(412,103) = HCF(515,412) = HCF(927,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 988 > 103, we apply the division lemma to 988 and 103, to get
988 = 103 x 9 + 61
Step 2: Since the reminder 103 ≠ 0, we apply division lemma to 61 and 103, to get
103 = 61 x 1 + 42
Step 3: We consider the new divisor 61 and the new remainder 42, and apply the division lemma to get
61 = 42 x 1 + 19
We consider the new divisor 42 and the new remainder 19,and apply the division lemma to get
42 = 19 x 2 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 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 103 and 988 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(42,19) = HCF(61,42) = HCF(103,61) = HCF(988,103) .
