HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 5350, 1825, 19365 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 5350, 1825, 19365 is 5 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 5350, 1825, 19365 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 5350, 1825, 19365 is 5.
HCF(5350, 1825, 19365) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 5350, 1825, 19365 is 5.
Step 1: Since 5350 > 1825, we apply the division lemma to 5350 and 1825, to get
5350 = 1825 x 2 + 1700
Step 2: Since the reminder 1825 ≠ 0, we apply division lemma to 1700 and 1825, to get
1825 = 1700 x 1 + 125
Step 3: We consider the new divisor 1700 and the new remainder 125, and apply the division lemma to get
1700 = 125 x 13 + 75
We consider the new divisor 125 and the new remainder 75,and apply the division lemma to get
125 = 75 x 1 + 50
We consider the new divisor 75 and the new remainder 50,and apply the division lemma to get
75 = 50 x 1 + 25
We consider the new divisor 50 and the new remainder 25,and apply the division lemma to get
50 = 25 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 5350 and 1825 is 25
Notice that 25 = HCF(50,25) = HCF(75,50) = HCF(125,75) = HCF(1700,125) = HCF(1825,1700) = HCF(5350,1825) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 19365 > 25, we apply the division lemma to 19365 and 25, to get
19365 = 25 x 774 + 15
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 15 and 25, to get
25 = 15 x 1 + 10
Step 3: We consider the new divisor 15 and the new remainder 10, and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 25 and 19365 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(19365,25) .
