HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 488, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 290, 488, 545 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 290, 488, 545 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 290, 488, 545 is 1.
HCF(290, 488, 545) = 1
HCF of 290, 488, 545 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 290, 488, 545 is 1.
Highest Common Factor of 290,488,545 is 1
Step 1: Since 488 > 290, we apply the division lemma to 488 and 290, to get
488 = 290 x 1 + 198
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 198 and 290, to get
290 = 198 x 1 + 92
Step 3: We consider the new divisor 198 and the new remainder 92, and apply the division lemma to get
198 = 92 x 2 + 14
We consider the new divisor 92 and the new remainder 14,and apply the division lemma to get
92 = 14 x 6 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 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 290 and 488 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(92,14) = HCF(198,92) = HCF(290,198) = HCF(488,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 545 > 2, we apply the division lemma to 545 and 2, to get
545 = 2 x 272 + 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 545 is 1
Notice that 1 = HCF(2,1) = HCF(545,2) .
