HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 993, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 447, 993, 580 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 447, 993, 580 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 447, 993, 580 is 1.
HCF(447, 993, 580) = 1
HCF of 447, 993, 580 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 447, 993, 580 is 1.
Highest Common Factor of 447,993,580 is 1
Step 1: Since 993 > 447, we apply the division lemma to 993 and 447, to get
993 = 447 x 2 + 99
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 99 and 447, to get
447 = 99 x 4 + 51
Step 3: We consider the new divisor 99 and the new remainder 51, and apply the division lemma to get
99 = 51 x 1 + 48
We consider the new divisor 51 and the new remainder 48,and apply the division lemma to get
51 = 48 x 1 + 3
We consider the new divisor 48 and the new remainder 3,and apply the division lemma to get
48 = 3 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 447 and 993 is 3
Notice that 3 = HCF(48,3) = HCF(51,48) = HCF(99,51) = HCF(447,99) = HCF(993,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 580 > 3, we apply the division lemma to 580 and 3, to get
580 = 3 x 193 + 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 580 is 1
Notice that 1 = HCF(3,1) = HCF(580,3) .
