HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 281, 609, 649, 111 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 281, 609, 649, 111 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 281, 609, 649, 111 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 281, 609, 649, 111 is 1.
HCF(281, 609, 649, 111) = 1
HCF of 281, 609, 649, 111 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 281, 609, 649, 111 is 1.
Highest Common Factor of 281,609,649,111 is 1
Step 1: Since 609 > 281, we apply the division lemma to 609 and 281, to get
609 = 281 x 2 + 47
Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 47 and 281, to get
281 = 47 x 5 + 46
Step 3: We consider the new divisor 47 and the new remainder 46, and apply the division lemma to get
47 = 46 x 1 + 1
We consider the new divisor 46 and the new remainder 1, and apply the division lemma to get
46 = 1 x 46 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 281 and 609 is 1
Notice that 1 = HCF(46,1) = HCF(47,46) = HCF(281,47) = HCF(609,281) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 649 > 1, we apply the division lemma to 649 and 1, to get
649 = 1 x 649 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 649 is 1
Notice that 1 = HCF(649,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 111 > 1, we apply the division lemma to 111 and 1, to get
111 = 1 x 111 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 111 is 1
Notice that 1 = HCF(111,1) .
