HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 248, 425, 724, 21 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 248, 425, 724, 21 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 248, 425, 724, 21 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 248, 425, 724, 21 is 1.
HCF(248, 425, 724, 21) = 1
HCF of 248, 425, 724, 21 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 248, 425, 724, 21 is 1.
Highest Common Factor of 248,425,724,21 is 1
Step 1: Since 425 > 248, we apply the division lemma to 425 and 248, to get
425 = 248 x 1 + 177
Step 2: Since the reminder 248 ≠ 0, we apply division lemma to 177 and 248, to get
248 = 177 x 1 + 71
Step 3: We consider the new divisor 177 and the new remainder 71, and apply the division lemma to get
177 = 71 x 2 + 35
We consider the new divisor 71 and the new remainder 35,and apply the division lemma to get
71 = 35 x 2 + 1
We consider the new divisor 35 and the new remainder 1,and apply the division lemma to get
35 = 1 x 35 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 248 and 425 is 1
Notice that 1 = HCF(35,1) = HCF(71,35) = HCF(177,71) = HCF(248,177) = HCF(425,248) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 1, we apply the division lemma to 724 and 1, to get
724 = 1 x 724 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 724 is 1
Notice that 1 = HCF(724,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 1, we apply the division lemma to 21 and 1, to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21 is 1
Notice that 1 = HCF(21,1) .
