HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 4893, 1568 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 4893, 1568 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, 4893, 1568 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, 4893, 1568 is 1.
HCF(654, 4893, 1568) = 1
HCF of 654, 4893, 1568 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 4893, 1568 is 1.
Highest Common Factor of 654,4893,1568 is 1
Step 1: Since 4893 > 654, we apply the division lemma to 4893 and 654, to get
4893 = 654 x 7 + 315
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 315 and 654, to get
654 = 315 x 2 + 24
Step 3: We consider the new divisor 315 and the new remainder 24, and apply the division lemma to get
315 = 24 x 13 + 3
We consider the new divisor 24 and the new remainder 3, and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 654 and 4893 is 3
Notice that 3 = HCF(24,3) = HCF(315,24) = HCF(654,315) = HCF(4893,654) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1568 > 3, we apply the division lemma to 1568 and 3, to get
1568 = 3 x 522 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 1568 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(1568,3) .
