HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 654, 737 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 654, 737 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 831, 654, 737 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 831, 654, 737 is 1.
HCF(831, 654, 737) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 654, 737 is 1.
Step 1: Since 831 > 654, we apply the division lemma to 831 and 654, to get
831 = 654 x 1 + 177
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 177 and 654, to get
654 = 177 x 3 + 123
Step 3: We consider the new divisor 177 and the new remainder 123, and apply the division lemma to get
177 = 123 x 1 + 54
We consider the new divisor 123 and the new remainder 54,and apply the division lemma to get
123 = 54 x 2 + 15
We consider the new divisor 54 and the new remainder 15,and apply the division lemma to get
54 = 15 x 3 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 654 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(123,54) = HCF(177,123) = HCF(654,177) = HCF(831,654) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 737 > 3, we apply the division lemma to 737 and 3, to get
737 = 3 x 245 + 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 737 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(737,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
