HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 987, 364, 804 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 987, 364, 804 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, 987, 364, 804 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, 987, 364, 804 is 1.
HCF(515, 987, 364, 804) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 987, 364, 804 is 1.
Step 1: Since 987 > 515, we apply the division lemma to 987 and 515, to get
987 = 515 x 1 + 472
Step 2: Since the reminder 515 ≠ 0, we apply division lemma to 472 and 515, to get
515 = 472 x 1 + 43
Step 3: We consider the new divisor 472 and the new remainder 43, and apply the division lemma to get
472 = 43 x 10 + 42
We consider the new divisor 43 and the new remainder 42,and apply the division lemma to get
43 = 42 x 1 + 1
We consider the new divisor 42 and the new remainder 1,and apply the division lemma to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 515 and 987 is 1
Notice that 1 = HCF(42,1) = HCF(43,42) = HCF(472,43) = HCF(515,472) = HCF(987,515) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 364 > 1, we apply the division lemma to 364 and 1, to get
364 = 1 x 364 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 364 is 1
Notice that 1 = HCF(364,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 804 > 1, we apply the division lemma to 804 and 1, to get
804 = 1 x 804 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 804 is 1
Notice that 1 = HCF(804,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
