HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 982, 728, 542 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 982, 728, 542 is 2 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 982, 728, 542 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 982, 728, 542 is 2.
HCF(982, 728, 542) = 2
HCF of 982, 728, 542 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 982, 728, 542 is 2.
Highest Common Factor of 982,728,542 is 2
Step 1: Since 982 > 728, we apply the division lemma to 982 and 728, to get
982 = 728 x 1 + 254
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 254 and 728, to get
728 = 254 x 2 + 220
Step 3: We consider the new divisor 254 and the new remainder 220, and apply the division lemma to get
254 = 220 x 1 + 34
We consider the new divisor 220 and the new remainder 34,and apply the division lemma to get
220 = 34 x 6 + 16
We consider the new divisor 34 and the new remainder 16,and apply the division lemma to get
34 = 16 x 2 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 982 and 728 is 2
Notice that 2 = HCF(16,2) = HCF(34,16) = HCF(220,34) = HCF(254,220) = HCF(728,254) = HCF(982,728) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 2, we apply the division lemma to 542 and 2, to get
542 = 2 x 271 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 542 is 2
Notice that 2 = HCF(542,2) .
