HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 578, 644, 675 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 578, 644, 675 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 180, 578, 644, 675 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 180, 578, 644, 675 is 1.
HCF(180, 578, 644, 675) = 1
HCF of 180, 578, 644, 675 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 578, 644, 675 is 1.
Highest Common Factor of 180,578,644,675 is 1
Step 1: Since 578 > 180, we apply the division lemma to 578 and 180, to get
578 = 180 x 3 + 38
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 38 and 180, to get
180 = 38 x 4 + 28
Step 3: We consider the new divisor 38 and the new remainder 28, and apply the division lemma to get
38 = 28 x 1 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 180 and 578 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(38,28) = HCF(180,38) = HCF(578,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 644 > 2, we apply the division lemma to 644 and 2, to get
644 = 2 x 322 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 644 is 2
Notice that 2 = HCF(644,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 675 > 2, we apply the division lemma to 675 and 2, to get
675 = 2 x 337 + 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 675 is 1
Notice that 1 = HCF(2,1) = HCF(675,2) .
