HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 262, 615, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 262, 615, 28 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 242, 262, 615, 28 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 242, 262, 615, 28 is 1.
HCF(242, 262, 615, 28) = 1
HCF of 242, 262, 615, 28 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 242, 262, 615, 28 is 1.
Highest Common Factor of 242,262,615,28 is 1
Step 1: Since 262 > 242, we apply the division lemma to 262 and 242, to get
262 = 242 x 1 + 20
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 20 and 242, to get
242 = 20 x 12 + 2
Step 3: We consider the new divisor 20 and the new remainder 2, and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 242 and 262 is 2
Notice that 2 = HCF(20,2) = HCF(242,20) = HCF(262,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 2, we apply the division lemma to 615 and 2, to get
615 = 2 x 307 + 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 615 is 1
Notice that 1 = HCF(2,1) = HCF(615,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1
Notice that 1 = HCF(28,1) .
