HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 620, 570 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 620, 570 is 10 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, 620, 570 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, 620, 570 is 10.
HCF(980, 620, 570) = 10
HCF of 980, 620, 570 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 620, 570 is 10.
Highest Common Factor of 980,620,570 is 10
Step 1: Since 980 > 620, we apply the division lemma to 980 and 620, to get
980 = 620 x 1 + 360
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 360 and 620, to get
620 = 360 x 1 + 260
Step 3: We consider the new divisor 360 and the new remainder 260, and apply the division lemma to get
360 = 260 x 1 + 100
We consider the new divisor 260 and the new remainder 100,and apply the division lemma to get
260 = 100 x 2 + 60
We consider the new divisor 100 and the new remainder 60,and apply the division lemma to get
100 = 60 x 1 + 40
We consider the new divisor 60 and the new remainder 40,and apply the division lemma to get
60 = 40 x 1 + 20
We consider the new divisor 40 and the new remainder 20,and apply the division lemma to get
40 = 20 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 980 and 620 is 20
Notice that 20 = HCF(40,20) = HCF(60,40) = HCF(100,60) = HCF(260,100) = HCF(360,260) = HCF(620,360) = HCF(980,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 570 > 20, we apply the division lemma to 570 and 20, to get
570 = 20 x 28 + 10
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 10 and 20, to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 20 and 570 is 10
Notice that 10 = HCF(20,10) = HCF(570,20) .
