HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 372, 696, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 372, 696, 815 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 372, 696, 815 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 372, 696, 815 is 1.
HCF(372, 696, 815) = 1
HCF of 372, 696, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 372, 696, 815 is 1.
Highest Common Factor of 372,696,815 is 1
Step 1: Since 696 > 372, we apply the division lemma to 696 and 372, to get
696 = 372 x 1 + 324
Step 2: Since the reminder 372 ≠ 0, we apply division lemma to 324 and 372, to get
372 = 324 x 1 + 48
Step 3: We consider the new divisor 324 and the new remainder 48, and apply the division lemma to get
324 = 48 x 6 + 36
We consider the new divisor 48 and the new remainder 36,and apply the division lemma to get
48 = 36 x 1 + 12
We consider the new divisor 36 and the new remainder 12,and apply the division lemma to get
36 = 12 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 372 and 696 is 12
Notice that 12 = HCF(36,12) = HCF(48,36) = HCF(324,48) = HCF(372,324) = HCF(696,372) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 12, we apply the division lemma to 815 and 12, to get
815 = 12 x 67 + 11
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 11 and 12, to get
12 = 11 x 1 + 1
Step 3: We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 815 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(815,12) .
