HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 69, 474, 380 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 69, 474, 380 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 69, 474, 380 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 69, 474, 380 is 1.
HCF(69, 474, 380) = 1
HCF of 69, 474, 380 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 69, 474, 380 is 1.
Highest Common Factor of 69,474,380 is 1
Step 1: Since 474 > 69, we apply the division lemma to 474 and 69, to get
474 = 69 x 6 + 60
Step 2: Since the reminder 69 ≠ 0, we apply division lemma to 60 and 69, to get
69 = 60 x 1 + 9
Step 3: We consider the new divisor 60 and the new remainder 9, and apply the division lemma to get
60 = 9 x 6 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 69 and 474 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(60,9) = HCF(69,60) = HCF(474,69) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 380 > 3, we apply the division lemma to 380 and 3, to get
380 = 3 x 126 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 380 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(380,3) .
