HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 862, 799, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 242, 862, 799, 861 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, 862, 799, 861 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, 862, 799, 861 is 1.
HCF(242, 862, 799, 861) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 242, 862, 799, 861 is 1.
Step 1: Since 862 > 242, we apply the division lemma to 862 and 242, to get
862 = 242 x 3 + 136
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 136 and 242, to get
242 = 136 x 1 + 106
Step 3: We consider the new divisor 136 and the new remainder 106, and apply the division lemma to get
136 = 106 x 1 + 30
We consider the new divisor 106 and the new remainder 30,and apply the division lemma to get
106 = 30 x 3 + 16
We consider the new divisor 30 and the new remainder 16,and apply the division lemma to get
30 = 16 x 1 + 14
We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 242 and 862 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(30,16) = HCF(106,30) = HCF(136,106) = HCF(242,136) = HCF(862,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 799 > 2, we apply the division lemma to 799 and 2, to get
799 = 2 x 399 + 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 799 is 1
Notice that 1 = HCF(2,1) = HCF(799,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get
861 = 1 x 861 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1
Notice that 1 = HCF(861,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
