HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 909, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 909, 623 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 558, 909, 623 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 558, 909, 623 is 1.
HCF(558, 909, 623) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 909, 623 is 1.
Step 1: Since 909 > 558, we apply the division lemma to 909 and 558, to get
909 = 558 x 1 + 351
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 351 and 558, to get
558 = 351 x 1 + 207
Step 3: We consider the new divisor 351 and the new remainder 207, and apply the division lemma to get
351 = 207 x 1 + 144
We consider the new divisor 207 and the new remainder 144,and apply the division lemma to get
207 = 144 x 1 + 63
We consider the new divisor 144 and the new remainder 63,and apply the division lemma to get
144 = 63 x 2 + 18
We consider the new divisor 63 and the new remainder 18,and apply the division lemma to get
63 = 18 x 3 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 558 and 909 is 9
Notice that 9 = HCF(18,9) = HCF(63,18) = HCF(144,63) = HCF(207,144) = HCF(351,207) = HCF(558,351) = HCF(909,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 623 > 9, we apply the division lemma to 623 and 9, to get
623 = 9 x 69 + 2
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 2 and 9, to get
9 = 2 x 4 + 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 9 and 623 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(623,9) .
Here are some samples of HCF using Euclid's Algorithm calculations.
