HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 579, 972, 843 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 579, 972, 843 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 579, 972, 843 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 579, 972, 843 is 3.
HCF(579, 972, 843) = 3
HCF of 579, 972, 843 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 579, 972, 843 is 3.
Highest Common Factor of 579,972,843 is 3
Step 1: Since 972 > 579, we apply the division lemma to 972 and 579, to get
972 = 579 x 1 + 393
Step 2: Since the reminder 579 ≠ 0, we apply division lemma to 393 and 579, to get
579 = 393 x 1 + 186
Step 3: We consider the new divisor 393 and the new remainder 186, and apply the division lemma to get
393 = 186 x 2 + 21
We consider the new divisor 186 and the new remainder 21,and apply the division lemma to get
186 = 21 x 8 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 579 and 972 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(186,21) = HCF(393,186) = HCF(579,393) = HCF(972,579) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 843 > 3, we apply the division lemma to 843 and 3, to get
843 = 3 x 281 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 843 is 3
Notice that 3 = HCF(843,3) .
