HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 430, 740 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 470, 430, 740 is 10 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 470, 430, 740 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 470, 430, 740 is 10.
HCF(470, 430, 740) = 10
HCF of 470, 430, 740 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 470, 430, 740 is 10.
Highest Common Factor of 470,430,740 is 10
Step 1: Since 470 > 430, we apply the division lemma to 470 and 430, to get
470 = 430 x 1 + 40
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 40 and 430, to get
430 = 40 x 10 + 30
Step 3: We consider the new divisor 40 and the new remainder 30, and apply the division lemma to get
40 = 30 x 1 + 10
We consider the new divisor 30 and the new remainder 10, and apply the division lemma to get
30 = 10 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 470 and 430 is 10
Notice that 10 = HCF(30,10) = HCF(40,30) = HCF(430,40) = HCF(470,430) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 740 > 10, we apply the division lemma to 740 and 10, to get
740 = 10 x 74 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 740 is 10
Notice that 10 = HCF(740,10) .
