HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 2519, 7825 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 126, 2519, 7825 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 126, 2519, 7825 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 126, 2519, 7825 is 1.
HCF(126, 2519, 7825) = 1
HCF of 126, 2519, 7825 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 126, 2519, 7825 is 1.
Highest Common Factor of 126,2519,7825 is 1
Step 1: Since 2519 > 126, we apply the division lemma to 2519 and 126, to get
2519 = 126 x 19 + 125
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 125 and 126, to get
126 = 125 x 1 + 1
Step 3: We consider the new divisor 125 and the new remainder 1, and apply the division lemma to get
125 = 1 x 125 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 126 and 2519 is 1
Notice that 1 = HCF(125,1) = HCF(126,125) = HCF(2519,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7825 > 1, we apply the division lemma to 7825 and 1, to get
7825 = 1 x 7825 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7825 is 1
Notice that 1 = HCF(7825,1) .
