HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 160, 1555, 1820 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 160, 1555, 1820 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 160, 1555, 1820 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 160, 1555, 1820 is 5.
HCF(160, 1555, 1820) = 5
HCF of 160, 1555, 1820 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 160, 1555, 1820 is 5.
Highest Common Factor of 160,1555,1820 is 5
Step 1: Since 1555 > 160, we apply the division lemma to 1555 and 160, to get
1555 = 160 x 9 + 115
Step 2: Since the reminder 160 ≠ 0, we apply division lemma to 115 and 160, to get
160 = 115 x 1 + 45
Step 3: We consider the new divisor 115 and the new remainder 45, and apply the division lemma to get
115 = 45 x 2 + 25
We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get
45 = 25 x 1 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 160 and 1555 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(115,45) = HCF(160,115) = HCF(1555,160) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1820 > 5, we apply the division lemma to 1820 and 5, to get
1820 = 5 x 364 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 1820 is 5
Notice that 5 = HCF(1820,5) .
