HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 703, 418, 399 i.e. 19 the largest integer that leaves a remainder zero for all numbers.
HCF of 703, 418, 399 is 19 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 703, 418, 399 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 703, 418, 399 is 19.
HCF(703, 418, 399) = 19
HCF of 703, 418, 399 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 703, 418, 399 is 19.
Highest Common Factor of 703,418,399 is 19
Step 1: Since 703 > 418, we apply the division lemma to 703 and 418, to get
703 = 418 x 1 + 285
Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 285 and 418, to get
418 = 285 x 1 + 133
Step 3: We consider the new divisor 285 and the new remainder 133, and apply the division lemma to get
285 = 133 x 2 + 19
We consider the new divisor 133 and the new remainder 19, and apply the division lemma to get
133 = 19 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 703 and 418 is 19
Notice that 19 = HCF(133,19) = HCF(285,133) = HCF(418,285) = HCF(703,418) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 399 > 19, we apply the division lemma to 399 and 19, to get
399 = 19 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 19 and 399 is 19
Notice that 19 = HCF(399,19) .
