HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 928, 998 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 542, 928, 998 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 542, 928, 998 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 542, 928, 998 is 2.
HCF(542, 928, 998) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 542, 928, 998 is 2.
Step 1: Since 928 > 542, we apply the division lemma to 928 and 542, to get
928 = 542 x 1 + 386
Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 386 and 542, to get
542 = 386 x 1 + 156
Step 3: We consider the new divisor 386 and the new remainder 156, and apply the division lemma to get
386 = 156 x 2 + 74
We consider the new divisor 156 and the new remainder 74,and apply the division lemma to get
156 = 74 x 2 + 8
We consider the new divisor 74 and the new remainder 8,and apply the division lemma to get
74 = 8 x 9 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 542 and 928 is 2
Notice that 2 = HCF(8,2) = HCF(74,8) = HCF(156,74) = HCF(386,156) = HCF(542,386) = HCF(928,542) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 998 > 2, we apply the division lemma to 998 and 2, to get
998 = 2 x 499 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 998 is 2
Notice that 2 = HCF(998,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
