HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 441, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 441, 76 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 615, 441, 76 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 615, 441, 76 is 1.
HCF(615, 441, 76) = 1
HCF of 615, 441, 76 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 441, 76 is 1.
Highest Common Factor of 615,441,76 is 1
Step 1: Since 615 > 441, we apply the division lemma to 615 and 441, to get
615 = 441 x 1 + 174
Step 2: Since the reminder 441 ≠ 0, we apply division lemma to 174 and 441, to get
441 = 174 x 2 + 93
Step 3: We consider the new divisor 174 and the new remainder 93, and apply the division lemma to get
174 = 93 x 1 + 81
We consider the new divisor 93 and the new remainder 81,and apply the division lemma to get
93 = 81 x 1 + 12
We consider the new divisor 81 and the new remainder 12,and apply the division lemma to get
81 = 12 x 6 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 441 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(81,12) = HCF(93,81) = HCF(174,93) = HCF(441,174) = HCF(615,441) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 3, we apply the division lemma to 76 and 3, to get
76 = 3 x 25 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 76 is 1
Notice that 1 = HCF(3,1) = HCF(76,3) .
