HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 580, 822, 973 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 580, 822, 973 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 580, 822, 973 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 580, 822, 973 is 1.
HCF(580, 822, 973) = 1
HCF of 580, 822, 973 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 580, 822, 973 is 1.
Highest Common Factor of 580,822,973 is 1
Step 1: Since 822 > 580, we apply the division lemma to 822 and 580, to get
822 = 580 x 1 + 242
Step 2: Since the reminder 580 ≠ 0, we apply division lemma to 242 and 580, to get
580 = 242 x 2 + 96
Step 3: We consider the new divisor 242 and the new remainder 96, and apply the division lemma to get
242 = 96 x 2 + 50
We consider the new divisor 96 and the new remainder 50,and apply the division lemma to get
96 = 50 x 1 + 46
We consider the new divisor 50 and the new remainder 46,and apply the division lemma to get
50 = 46 x 1 + 4
We consider the new divisor 46 and the new remainder 4,and apply the division lemma to get
46 = 4 x 11 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 580 and 822 is 2
Notice that 2 = HCF(4,2) = HCF(46,4) = HCF(50,46) = HCF(96,50) = HCF(242,96) = HCF(580,242) = HCF(822,580) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 2, we apply the division lemma to 973 and 2, to get
973 = 2 x 486 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 973 is 1
Notice that 1 = HCF(2,1) = HCF(973,2) .
