HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 849, 693, 984 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 849, 693, 984 is 3 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 849, 693, 984 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 849, 693, 984 is 3.
HCF(849, 693, 984) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 849, 693, 984 is 3.
Step 1: Since 849 > 693, we apply the division lemma to 849 and 693, to get
849 = 693 x 1 + 156
Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 156 and 693, to get
693 = 156 x 4 + 69
Step 3: We consider the new divisor 156 and the new remainder 69, and apply the division lemma to get
156 = 69 x 2 + 18
We consider the new divisor 69 and the new remainder 18,and apply the division lemma to get
69 = 18 x 3 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 849 and 693 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(69,18) = HCF(156,69) = HCF(693,156) = HCF(849,693) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 984 > 3, we apply the division lemma to 984 and 3, to get
984 = 3 x 328 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 984 is 3
Notice that 3 = HCF(984,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
