HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 315, 984 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 315, 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 858, 315, 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 858, 315, 984 is 3.
HCF(858, 315, 984) = 3
HCF of 858, 315, 984 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 315, 984 is 3.
Highest Common Factor of 858,315,984 is 3
Step 1: Since 858 > 315, we apply the division lemma to 858 and 315, to get
858 = 315 x 2 + 228
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 228 and 315, to get
315 = 228 x 1 + 87
Step 3: We consider the new divisor 228 and the new remainder 87, and apply the division lemma to get
228 = 87 x 2 + 54
We consider the new divisor 87 and the new remainder 54,and apply the division lemma to get
87 = 54 x 1 + 33
We consider the new divisor 54 and the new remainder 33,and apply the division lemma to get
54 = 33 x 1 + 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 858 and 315 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(54,33) = HCF(87,54) = HCF(228,87) = HCF(315,228) = HCF(858,315) .
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) .
