HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 158, 2419, 7225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 158, 2419, 7225 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 158, 2419, 7225 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 158, 2419, 7225 is 1.
HCF(158, 2419, 7225) = 1
HCF of 158, 2419, 7225 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 158, 2419, 7225 is 1.
Highest Common Factor of 158,2419,7225 is 1
Step 1: Since 2419 > 158, we apply the division lemma to 2419 and 158, to get
2419 = 158 x 15 + 49
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 49 and 158, to get
158 = 49 x 3 + 11
Step 3: We consider the new divisor 49 and the new remainder 11, and apply the division lemma to get
49 = 11 x 4 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 158 and 2419 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(49,11) = HCF(158,49) = HCF(2419,158) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7225 > 1, we apply the division lemma to 7225 and 1, to get
7225 = 1 x 7225 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7225 is 1
Notice that 1 = HCF(7225,1) .
