HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 948, 741, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 948, 741, 551 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 948, 741, 551 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 948, 741, 551 is 1.
HCF(948, 741, 551) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 948, 741, 551 is 1.
Step 1: Since 948 > 741, we apply the division lemma to 948 and 741, to get
948 = 741 x 1 + 207
Step 2: Since the reminder 741 ≠ 0, we apply division lemma to 207 and 741, to get
741 = 207 x 3 + 120
Step 3: We consider the new divisor 207 and the new remainder 120, and apply the division lemma to get
207 = 120 x 1 + 87
We consider the new divisor 120 and the new remainder 87,and apply the division lemma to get
120 = 87 x 1 + 33
We consider the new divisor 87 and the new remainder 33,and apply the division lemma to get
87 = 33 x 2 + 21
We consider the new divisor 33 and the new remainder 21,and apply the division lemma to get
33 = 21 x 1 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 948 and 741 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(87,33) = HCF(120,87) = HCF(207,120) = HCF(741,207) = HCF(948,741) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 551 > 3, we apply the division lemma to 551 and 3, to get
551 = 3 x 183 + 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 551 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(551,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
