HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 492, 585 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 492, 585 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 780, 492, 585 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 780, 492, 585 is 3.
HCF(780, 492, 585) = 3
HCF of 780, 492, 585 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 492, 585 is 3.
Highest Common Factor of 780,492,585 is 3
Step 1: Since 780 > 492, we apply the division lemma to 780 and 492, to get
780 = 492 x 1 + 288
Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 288 and 492, to get
492 = 288 x 1 + 204
Step 3: We consider the new divisor 288 and the new remainder 204, and apply the division lemma to get
288 = 204 x 1 + 84
We consider the new divisor 204 and the new remainder 84,and apply the division lemma to get
204 = 84 x 2 + 36
We consider the new divisor 84 and the new remainder 36,and apply the division lemma to get
84 = 36 x 2 + 12
We consider the new divisor 36 and the new remainder 12,and apply the division lemma to get
36 = 12 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 780 and 492 is 12
Notice that 12 = HCF(36,12) = HCF(84,36) = HCF(204,84) = HCF(288,204) = HCF(492,288) = HCF(780,492) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 585 > 12, we apply the division lemma to 585 and 12, to get
585 = 12 x 48 + 9
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 9 and 12, to get
12 = 9 x 1 + 3
Step 3: We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 12 and 585 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(585,12) .
