HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 416, 874 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 416, 874 is 2 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, 416, 874 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, 416, 874 is 2.
HCF(242, 416, 874) = 2
HCF of 242, 416, 874 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, 416, 874 is 2.
Highest Common Factor of 242,416,874 is 2
Step 1: Since 416 > 242, we apply the division lemma to 416 and 242, to get
416 = 242 x 1 + 174
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 174 and 242, to get
242 = 174 x 1 + 68
Step 3: We consider the new divisor 174 and the new remainder 68, and apply the division lemma to get
174 = 68 x 2 + 38
We consider the new divisor 68 and the new remainder 38,and apply the division lemma to get
68 = 38 x 1 + 30
We consider the new divisor 38 and the new remainder 30,and apply the division lemma to get
38 = 30 x 1 + 8
We consider the new divisor 30 and the new remainder 8,and apply the division lemma to get
30 = 8 x 3 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 242 and 416 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(30,8) = HCF(38,30) = HCF(68,38) = HCF(174,68) = HCF(242,174) = HCF(416,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 874 > 2, we apply the division lemma to 874 and 2, to get
874 = 2 x 437 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 874 is 2
Notice that 2 = HCF(874,2) .
