HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 518, 365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 974, 518, 365 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 974, 518, 365 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 974, 518, 365 is 1.
HCF(974, 518, 365) = 1
HCF of 974, 518, 365 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 974, 518, 365 is 1.
Highest Common Factor of 974,518,365 is 1
Step 1: Since 974 > 518, we apply the division lemma to 974 and 518, to get
974 = 518 x 1 + 456
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 456 and 518, to get
518 = 456 x 1 + 62
Step 3: We consider the new divisor 456 and the new remainder 62, and apply the division lemma to get
456 = 62 x 7 + 22
We consider the new divisor 62 and the new remainder 22,and apply the division lemma to get
62 = 22 x 2 + 18
We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get
22 = 18 x 1 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 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 974 and 518 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(62,22) = HCF(456,62) = HCF(518,456) = HCF(974,518) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 365 > 2, we apply the division lemma to 365 and 2, to get
365 = 2 x 182 + 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 365 is 1
Notice that 1 = HCF(2,1) = HCF(365,2) .
