HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 496, 1978, 7369 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 496, 1978, 7369 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, 1978, 7369 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, 1978, 7369 is 1.
HCF(496, 1978, 7369) = 1
HCF of 496, 1978, 7369 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, 1978, 7369 is 1.
Highest Common Factor of 496,1978,7369 is 1
Step 1: Since 1978 > 496, we apply the division lemma to 1978 and 496, to get
1978 = 496 x 3 + 490
Step 2: Since the reminder 496 ≠ 0, we apply division lemma to 490 and 496, to get
496 = 490 x 1 + 6
Step 3: We consider the new divisor 490 and the new remainder 6, and apply the division lemma to get
490 = 6 x 81 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 496 and 1978 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(490,6) = HCF(496,490) = HCF(1978,496) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7369 > 2, we apply the division lemma to 7369 and 2, to get
7369 = 2 x 3684 + 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 7369 is 1
Notice that 1 = HCF(2,1) = HCF(7369,2) .
