HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 430, 720 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 430, 720 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 430, 720 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 430, 720 is 10.
HCF(430, 720) = 10
HCF of 430, 720 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 430, 720 is 10.
Highest Common Factor of 430,720 is 10
Step 1: Since 720 > 430, we apply the division lemma to 720 and 430, to get
720 = 430 x 1 + 290
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 290 and 430, to get
430 = 290 x 1 + 140
Step 3: We consider the new divisor 290 and the new remainder 140, and apply the division lemma to get
290 = 140 x 2 + 10
We consider the new divisor 140 and the new remainder 10, and apply the division lemma to get
140 = 10 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 430 and 720 is 10
Notice that 10 = HCF(140,10) = HCF(290,140) = HCF(430,290) = HCF(720,430) .
