HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 560, 153, 261 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 818, 560, 153, 261 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 818, 560, 153, 261 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 818, 560, 153, 261 is 1.
HCF(818, 560, 153, 261) = 1
HCF of 818, 560, 153, 261 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 818, 560, 153, 261 is 1.
Highest Common Factor of 818,560,153,261 is 1
Step 1: Since 818 > 560, we apply the division lemma to 818 and 560, to get
818 = 560 x 1 + 258
Step 2: Since the reminder 560 ≠ 0, we apply division lemma to 258 and 560, to get
560 = 258 x 2 + 44
Step 3: We consider the new divisor 258 and the new remainder 44, and apply the division lemma to get
258 = 44 x 5 + 38
We consider the new divisor 44 and the new remainder 38,and apply the division lemma to get
44 = 38 x 1 + 6
We consider the new divisor 38 and the new remainder 6,and apply the division lemma to get
38 = 6 x 6 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 818 and 560 is 2
Notice that 2 = HCF(6,2) = HCF(38,6) = HCF(44,38) = HCF(258,44) = HCF(560,258) = HCF(818,560) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 153 > 2, we apply the division lemma to 153 and 2, to get
153 = 2 x 76 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 153 is 1
Notice that 1 = HCF(2,1) = HCF(153,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 261 > 1, we apply the division lemma to 261 and 1, to get
261 = 1 x 261 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 261 is 1
Notice that 1 = HCF(261,1) .
