HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 800, 59, 559 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 800, 59, 559 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 980, 800, 59, 559 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 980, 800, 59, 559 is 1.
HCF(980, 800, 59, 559) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 800, 59, 559 is 1.
Step 1: Since 980 > 800, we apply the division lemma to 980 and 800, to get
980 = 800 x 1 + 180
Step 2: Since the reminder 800 ≠ 0, we apply division lemma to 180 and 800, to get
800 = 180 x 4 + 80
Step 3: We consider the new divisor 180 and the new remainder 80, and apply the division lemma to get
180 = 80 x 2 + 20
We consider the new divisor 80 and the new remainder 20, and apply the division lemma to get
80 = 20 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 980 and 800 is 20
Notice that 20 = HCF(80,20) = HCF(180,80) = HCF(800,180) = HCF(980,800) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 20, we apply the division lemma to 59 and 20, to get
59 = 20 x 2 + 19
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 19 and 20, to get
20 = 19 x 1 + 1
Step 3: We consider the new divisor 19 and the new remainder 1, and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 20 and 59 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(59,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 559 > 1, we apply the division lemma to 559 and 1, to get
559 = 1 x 559 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 559 is 1
Notice that 1 = HCF(559,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
