HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 610 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 610 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 390, 610 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 390, 610 is 10.
HCF(390, 610) = 10
HCF of 390, 610 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 610 is 10.
Highest Common Factor of 390,610 is 10
Step 1: Since 610 > 390, we apply the division lemma to 610 and 390, to get
610 = 390 x 1 + 220
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 220 and 390, to get
390 = 220 x 1 + 170
Step 3: We consider the new divisor 220 and the new remainder 170, and apply the division lemma to get
220 = 170 x 1 + 50
We consider the new divisor 170 and the new remainder 50,and apply the division lemma to get
170 = 50 x 3 + 20
We consider the new divisor 50 and the new remainder 20,and apply the division lemma to get
50 = 20 x 2 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 390 and 610 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(170,50) = HCF(220,170) = HCF(390,220) = HCF(610,390) .
