HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 938 i.e. 14 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 938 is 14 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 518, 938 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 518, 938 is 14.
HCF(518, 938) = 14
HCF of 518, 938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 518, 938 is 14.
Highest Common Factor of 518,938 is 14
Step 1: Since 938 > 518, we apply the division lemma to 938 and 518, to get
938 = 518 x 1 + 420
Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 420 and 518, to get
518 = 420 x 1 + 98
Step 3: We consider the new divisor 420 and the new remainder 98, and apply the division lemma to get
420 = 98 x 4 + 28
We consider the new divisor 98 and the new remainder 28,and apply the division lemma to get
98 = 28 x 3 + 14
We consider the new divisor 28 and the new remainder 14,and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 518 and 938 is 14
Notice that 14 = HCF(28,14) = HCF(98,28) = HCF(420,98) = HCF(518,420) = HCF(938,518) .
