HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 553, 766, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 553, 766, 447 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 997, 553, 766, 447 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 997, 553, 766, 447 is 1.
HCF(997, 553, 766, 447) = 1
HCF of 997, 553, 766, 447 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 553, 766, 447 is 1.
Highest Common Factor of 997,553,766,447 is 1
Step 1: Since 997 > 553, we apply the division lemma to 997 and 553, to get
997 = 553 x 1 + 444
Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 444 and 553, to get
553 = 444 x 1 + 109
Step 3: We consider the new divisor 444 and the new remainder 109, and apply the division lemma to get
444 = 109 x 4 + 8
We consider the new divisor 109 and the new remainder 8,and apply the division lemma to get
109 = 8 x 13 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 997 and 553 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(109,8) = HCF(444,109) = HCF(553,444) = HCF(997,553) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 766 > 1, we apply the division lemma to 766 and 1, to get
766 = 1 x 766 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 766 is 1
Notice that 1 = HCF(766,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 447 > 1, we apply the division lemma to 447 and 1, to get
447 = 1 x 447 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 447 is 1
Notice that 1 = HCF(447,1) .
