HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 472, 546, 78 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 472, 546, 78 is 2 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 472, 546, 78 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 472, 546, 78 is 2.
HCF(472, 546, 78) = 2
HCF of 472, 546, 78 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 472, 546, 78 is 2.
Highest Common Factor of 472,546,78 is 2
Step 1: Since 546 > 472, we apply the division lemma to 546 and 472, to get
546 = 472 x 1 + 74
Step 2: Since the reminder 472 ≠ 0, we apply division lemma to 74 and 472, to get
472 = 74 x 6 + 28
Step 3: We consider the new divisor 74 and the new remainder 28, and apply the division lemma to get
74 = 28 x 2 + 18
We consider the new divisor 28 and the new remainder 18,and apply the division lemma to get
28 = 18 x 1 + 10
We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get
18 = 10 x 1 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 472 and 546 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(28,18) = HCF(74,28) = HCF(472,74) = HCF(546,472) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 2, we apply the division lemma to 78 and 2, to get
78 = 2 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 78 is 2
Notice that 2 = HCF(78,2) .
