HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 954, 789, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 954, 789, 802 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 954, 789, 802 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 954, 789, 802 is 1.
HCF(954, 789, 802) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 954, 789, 802 is 1.
Step 1: Since 954 > 789, we apply the division lemma to 954 and 789, to get
954 = 789 x 1 + 165
Step 2: Since the reminder 789 ≠ 0, we apply division lemma to 165 and 789, to get
789 = 165 x 4 + 129
Step 3: We consider the new divisor 165 and the new remainder 129, and apply the division lemma to get
165 = 129 x 1 + 36
We consider the new divisor 129 and the new remainder 36,and apply the division lemma to get
129 = 36 x 3 + 21
We consider the new divisor 36 and the new remainder 21,and apply the division lemma to get
36 = 21 x 1 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 954 and 789 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(36,21) = HCF(129,36) = HCF(165,129) = HCF(789,165) = HCF(954,789) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 3, we apply the division lemma to 802 and 3, to get
802 = 3 x 267 + 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 802 is 1
Notice that 1 = HCF(3,1) = HCF(802,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
