HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 402 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 402 is 2 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 742, 402 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 742, 402 is 2.
HCF(742, 402) = 2
HCF of 742, 402 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 402 is 2.
Highest Common Factor of 742,402 is 2
Step 1: Since 742 > 402, we apply the division lemma to 742 and 402, to get
742 = 402 x 1 + 340
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 340 and 402, to get
402 = 340 x 1 + 62
Step 3: We consider the new divisor 340 and the new remainder 62, and apply the division lemma to get
340 = 62 x 5 + 30
We consider the new divisor 62 and the new remainder 30,and apply the division lemma to get
62 = 30 x 2 + 2
We consider the new divisor 30 and the new remainder 2,and apply the division lemma to get
30 = 2 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 742 and 402 is 2
Notice that 2 = HCF(30,2) = HCF(62,30) = HCF(340,62) = HCF(402,340) = HCF(742,402) .
