HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 248, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 248, 961 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 618, 248, 961 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 618, 248, 961 is 1.
HCF(618, 248, 961) = 1
HCF of 618, 248, 961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 248, 961 is 1.
Highest Common Factor of 618,248,961 is 1
Step 1: Since 618 > 248, we apply the division lemma to 618 and 248, to get
618 = 248 x 2 + 122
Step 2: Since the reminder 248 ≠ 0, we apply division lemma to 122 and 248, to get
248 = 122 x 2 + 4
Step 3: We consider the new divisor 122 and the new remainder 4, and apply the division lemma to get
122 = 4 x 30 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 618 and 248 is 2
Notice that 2 = HCF(4,2) = HCF(122,4) = HCF(248,122) = HCF(618,248) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 961 > 2, we apply the division lemma to 961 and 2, to get
961 = 2 x 480 + 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 961 is 1
Notice that 1 = HCF(2,1) = HCF(961,2) .
