HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 546, 628, 38 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 546, 628, 38 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 546, 628, 38 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 546, 628, 38 is 2.
HCF(546, 628, 38) = 2
HCF of 546, 628, 38 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 546, 628, 38 is 2.
Highest Common Factor of 546,628,38 is 2
Step 1: Since 628 > 546, we apply the division lemma to 628 and 546, to get
628 = 546 x 1 + 82
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 82 and 546, to get
546 = 82 x 6 + 54
Step 3: We consider the new divisor 82 and the new remainder 54, and apply the division lemma to get
82 = 54 x 1 + 28
We consider the new divisor 54 and the new remainder 28,and apply the division lemma to get
54 = 28 x 1 + 26
We consider the new divisor 28 and the new remainder 26,and apply the division lemma to get
28 = 26 x 1 + 2
We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get
26 = 2 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 546 and 628 is 2
Notice that 2 = HCF(26,2) = HCF(28,26) = HCF(54,28) = HCF(82,54) = HCF(546,82) = HCF(628,546) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 2, we apply the division lemma to 38 and 2, to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 38 is 2
Notice that 2 = HCF(38,2) .
