HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 815, 976, 501 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 815, 976, 501 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 815, 976, 501 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 815, 976, 501 is 1.
HCF(815, 976, 501) = 1
HCF of 815, 976, 501 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 815, 976, 501 is 1.
Highest Common Factor of 815,976,501 is 1
Step 1: Since 976 > 815, we apply the division lemma to 976 and 815, to get
976 = 815 x 1 + 161
Step 2: Since the reminder 815 ≠ 0, we apply division lemma to 161 and 815, to get
815 = 161 x 5 + 10
Step 3: We consider the new divisor 161 and the new remainder 10, and apply the division lemma to get
161 = 10 x 16 + 1
We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 815 and 976 is 1
Notice that 1 = HCF(10,1) = HCF(161,10) = HCF(815,161) = HCF(976,815) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 501 > 1, we apply the division lemma to 501 and 1, to get
501 = 1 x 501 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 501 is 1
Notice that 1 = HCF(501,1) .
