HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 990, 429 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 990, 429 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 585, 990, 429 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 585, 990, 429 is 3.
HCF(585, 990, 429) = 3
HCF of 585, 990, 429 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 990, 429 is 3.
Highest Common Factor of 585,990,429 is 3
Step 1: Since 990 > 585, we apply the division lemma to 990 and 585, to get
990 = 585 x 1 + 405
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 405 and 585, to get
585 = 405 x 1 + 180
Step 3: We consider the new divisor 405 and the new remainder 180, and apply the division lemma to get
405 = 180 x 2 + 45
We consider the new divisor 180 and the new remainder 45, and apply the division lemma to get
180 = 45 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 585 and 990 is 45
Notice that 45 = HCF(180,45) = HCF(405,180) = HCF(585,405) = HCF(990,585) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 429 > 45, we apply the division lemma to 429 and 45, to get
429 = 45 x 9 + 24
Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 24 and 45, to get
45 = 24 x 1 + 21
Step 3: We consider the new divisor 24 and the new remainder 21, and apply the division lemma to get
24 = 21 x 1 + 3
We consider the new divisor 21 and the new remainder 3, and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 45 and 429 is 3
Notice that 3 = HCF(21,3) = HCF(24,21) = HCF(45,24) = HCF(429,45) .
