HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 792, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 792, 565 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, 792, 565 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, 792, 565 is 1.
HCF(558, 792, 565) = 1
HCF of 558, 792, 565 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 792, 565 is 1.
Highest Common Factor of 558,792,565 is 1
Step 1: Since 792 > 558, we apply the division lemma to 792 and 558, to get
792 = 558 x 1 + 234
Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 234 and 558, to get
558 = 234 x 2 + 90
Step 3: We consider the new divisor 234 and the new remainder 90, and apply the division lemma to get
234 = 90 x 2 + 54
We consider the new divisor 90 and the new remainder 54,and apply the division lemma to get
90 = 54 x 1 + 36
We consider the new divisor 54 and the new remainder 36,and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 558 and 792 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(90,54) = HCF(234,90) = HCF(558,234) = HCF(792,558) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 565 > 18, we apply the division lemma to 565 and 18, to get
565 = 18 x 31 + 7
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 7 and 18, to get
18 = 7 x 2 + 4
Step 3: We consider the new divisor 7 and the new remainder 4, and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 18 and 565 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(565,18) .
