HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 948, 15, 242 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 948, 15, 242 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 948, 15, 242 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 948, 15, 242 is 1.
HCF(948, 15, 242) = 1
HCF of 948, 15, 242 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 948, 15, 242 is 1.
Highest Common Factor of 948,15,242 is 1
Step 1: Since 948 > 15, we apply the division lemma to 948 and 15, to get
948 = 15 x 63 + 3
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 3 and 15, to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 948 and 15 is 3
Notice that 3 = HCF(15,3) = HCF(948,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 242 > 3, we apply the division lemma to 242 and 3, to get
242 = 3 x 80 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 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 3 and 242 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(242,3) .
