HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 681, 468, 564 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 285, 681, 468, 564 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 285, 681, 468, 564 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 285, 681, 468, 564 is 3.
HCF(285, 681, 468, 564) = 3
HCF of 285, 681, 468, 564 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 285, 681, 468, 564 is 3.
Highest Common Factor of 285,681,468,564 is 3
Step 1: Since 681 > 285, we apply the division lemma to 681 and 285, to get
681 = 285 x 2 + 111
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 111 and 285, to get
285 = 111 x 2 + 63
Step 3: We consider the new divisor 111 and the new remainder 63, and apply the division lemma to get
111 = 63 x 1 + 48
We consider the new divisor 63 and the new remainder 48,and apply the division lemma to get
63 = 48 x 1 + 15
We consider the new divisor 48 and the new remainder 15,and apply the division lemma to get
48 = 15 x 3 + 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 285 and 681 is 3
Notice that 3 = HCF(15,3) = HCF(48,15) = HCF(63,48) = HCF(111,63) = HCF(285,111) = HCF(681,285) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 3, we apply the division lemma to 468 and 3, to get
468 = 3 x 156 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 468 is 3
Notice that 3 = HCF(468,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 564 > 3, we apply the division lemma to 564 and 3, to get
564 = 3 x 188 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 564 is 3
Notice that 3 = HCF(564,3) .
