HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 489, 573 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 489, 573 is 3 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 825, 489, 573 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 825, 489, 573 is 3.
HCF(825, 489, 573) = 3
HCF of 825, 489, 573 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 489, 573 is 3.
Highest Common Factor of 825,489,573 is 3
Step 1: Since 825 > 489, we apply the division lemma to 825 and 489, to get
825 = 489 x 1 + 336
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 336 and 489, to get
489 = 336 x 1 + 153
Step 3: We consider the new divisor 336 and the new remainder 153, and apply the division lemma to get
336 = 153 x 2 + 30
We consider the new divisor 153 and the new remainder 30,and apply the division lemma to get
153 = 30 x 5 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 825 and 489 is 3
Notice that 3 = HCF(30,3) = HCF(153,30) = HCF(336,153) = HCF(489,336) = HCF(825,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 573 > 3, we apply the division lemma to 573 and 3, to get
573 = 3 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 573 is 3
Notice that 3 = HCF(573,3) .
