HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7916, 3921, 31415 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7916, 3921, 31415 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 7916, 3921, 31415 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 7916, 3921, 31415 is 1.
HCF(7916, 3921, 31415) = 1
HCF of 7916, 3921, 31415 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7916, 3921, 31415 is 1.
Highest Common Factor of 7916,3921,31415 is 1
Step 1: Since 7916 > 3921, we apply the division lemma to 7916 and 3921, to get
7916 = 3921 x 2 + 74
Step 2: Since the reminder 3921 ≠ 0, we apply division lemma to 74 and 3921, to get
3921 = 74 x 52 + 73
Step 3: We consider the new divisor 74 and the new remainder 73, and apply the division lemma to get
74 = 73 x 1 + 1
We consider the new divisor 73 and the new remainder 1, and apply the division lemma to get
73 = 1 x 73 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7916 and 3921 is 1
Notice that 1 = HCF(73,1) = HCF(74,73) = HCF(3921,74) = HCF(7916,3921) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31415 > 1, we apply the division lemma to 31415 and 1, to get
31415 = 1 x 31415 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31415 is 1
Notice that 1 = HCF(31415,1) .
