HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4545, 6573 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 4545, 6573 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 4545, 6573 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 4545, 6573 is 3.
HCF(4545, 6573) = 3
HCF of 4545, 6573 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4545, 6573 is 3.
Highest Common Factor of 4545,6573 is 3
Step 1: Since 6573 > 4545, we apply the division lemma to 6573 and 4545, to get
6573 = 4545 x 1 + 2028
Step 2: Since the reminder 4545 ≠ 0, we apply division lemma to 2028 and 4545, to get
4545 = 2028 x 2 + 489
Step 3: We consider the new divisor 2028 and the new remainder 489, and apply the division lemma to get
2028 = 489 x 4 + 72
We consider the new divisor 489 and the new remainder 72,and apply the division lemma to get
489 = 72 x 6 + 57
We consider the new divisor 72 and the new remainder 57,and apply the division lemma to get
72 = 57 x 1 + 15
We consider the new divisor 57 and the new remainder 15,and apply the division lemma to get
57 = 15 x 3 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 4545 and 6573 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(57,15) = HCF(72,57) = HCF(489,72) = HCF(2028,489) = HCF(4545,2028) = HCF(6573,4545) .
