HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 797, 909, 792 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 797, 909, 792 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 654, 797, 909, 792 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 654, 797, 909, 792 is 1.
HCF(654, 797, 909, 792) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 797, 909, 792 is 1.
Step 1: Since 797 > 654, we apply the division lemma to 797 and 654, to get
797 = 654 x 1 + 143
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 143 and 654, to get
654 = 143 x 4 + 82
Step 3: We consider the new divisor 143 and the new remainder 82, and apply the division lemma to get
143 = 82 x 1 + 61
We consider the new divisor 82 and the new remainder 61,and apply the division lemma to get
82 = 61 x 1 + 21
We consider the new divisor 61 and the new remainder 21,and apply the division lemma to get
61 = 21 x 2 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 654 and 797 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(61,21) = HCF(82,61) = HCF(143,82) = HCF(654,143) = HCF(797,654) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 1, we apply the division lemma to 909 and 1, to get
909 = 1 x 909 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 909 is 1
Notice that 1 = HCF(909,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 792 > 1, we apply the division lemma to 792 and 1, to get
792 = 1 x 792 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 792 is 1
Notice that 1 = HCF(792,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
