HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 496, 298, 840, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 496, 298, 840, 815 is 1 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 496, 298, 840, 815 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 496, 298, 840, 815 is 1.
HCF(496, 298, 840, 815) = 1
HCF of 496, 298, 840, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 496, 298, 840, 815 is 1.
Highest Common Factor of 496,298,840,815 is 1
Step 1: Since 496 > 298, we apply the division lemma to 496 and 298, to get
496 = 298 x 1 + 198
Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 198 and 298, to get
298 = 198 x 1 + 100
Step 3: We consider the new divisor 198 and the new remainder 100, and apply the division lemma to get
198 = 100 x 1 + 98
We consider the new divisor 100 and the new remainder 98,and apply the division lemma to get
100 = 98 x 1 + 2
We consider the new divisor 98 and the new remainder 2,and apply the division lemma to get
98 = 2 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 496 and 298 is 2
Notice that 2 = HCF(98,2) = HCF(100,98) = HCF(198,100) = HCF(298,198) = HCF(496,298) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 840 > 2, we apply the division lemma to 840 and 2, to get
840 = 2 x 420 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 840 is 2
Notice that 2 = HCF(840,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 2, we apply the division lemma to 815 and 2, to get
815 = 2 x 407 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 815 is 1
Notice that 1 = HCF(2,1) = HCF(815,2) .
