HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 955, 421, 288 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 955, 421, 288 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 955, 421, 288 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 955, 421, 288 is 1.
HCF(955, 421, 288) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 955, 421, 288 is 1.
Step 1: Since 955 > 421, we apply the division lemma to 955 and 421, to get
955 = 421 x 2 + 113
Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 113 and 421, to get
421 = 113 x 3 + 82
Step 3: We consider the new divisor 113 and the new remainder 82, and apply the division lemma to get
113 = 82 x 1 + 31
We consider the new divisor 82 and the new remainder 31,and apply the division lemma to get
82 = 31 x 2 + 20
We consider the new divisor 31 and the new remainder 20,and apply the division lemma to get
31 = 20 x 1 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
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 955 and 421 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(31,20) = HCF(82,31) = HCF(113,82) = HCF(421,113) = HCF(955,421) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 1, we apply the division lemma to 288 and 1, to get
288 = 1 x 288 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 288 is 1
Notice that 1 = HCF(288,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
