HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 749, 406 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 749, 406 is 7 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 749, 406 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 749, 406 is 7.
HCF(749, 406) = 7
HCF of 749, 406 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 749, 406 is 7.
Highest Common Factor of 749,406 is 7
Step 1: Since 749 > 406, we apply the division lemma to 749 and 406, to get
749 = 406 x 1 + 343
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 343 and 406, to get
406 = 343 x 1 + 63
Step 3: We consider the new divisor 343 and the new remainder 63, and apply the division lemma to get
343 = 63 x 5 + 28
We consider the new divisor 63 and the new remainder 28,and apply the division lemma to get
63 = 28 x 2 + 7
We consider the new divisor 28 and the new remainder 7,and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 749 and 406 is 7
Notice that 7 = HCF(28,7) = HCF(63,28) = HCF(343,63) = HCF(406,343) = HCF(749,406) .
