HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 612, 489, 822 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 612, 489, 822 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 612, 489, 822 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 612, 489, 822 is 3.
HCF(612, 489, 822) = 3
HCF of 612, 489, 822 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 612, 489, 822 is 3.
Highest Common Factor of 612,489,822 is 3
Step 1: Since 612 > 489, we apply the division lemma to 612 and 489, to get
612 = 489 x 1 + 123
Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 123 and 489, to get
489 = 123 x 3 + 120
Step 3: We consider the new divisor 123 and the new remainder 120, and apply the division lemma to get
123 = 120 x 1 + 3
We consider the new divisor 120 and the new remainder 3, and apply the division lemma to get
120 = 3 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 612 and 489 is 3
Notice that 3 = HCF(120,3) = HCF(123,120) = HCF(489,123) = HCF(612,489) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 822 > 3, we apply the division lemma to 822 and 3, to get
822 = 3 x 274 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 822 is 3
Notice that 3 = HCF(822,3) .
