HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 807, 621 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 470, 807, 621 is 1 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, 807, 621 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, 807, 621 is 1.
HCF(470, 807, 621) = 1
HCF of 470, 807, 621 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, 807, 621 is 1.
Highest Common Factor of 470,807,621 is 1
Step 1: Since 807 > 470, we apply the division lemma to 807 and 470, to get
807 = 470 x 1 + 337
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 337 and 470, to get
470 = 337 x 1 + 133
Step 3: We consider the new divisor 337 and the new remainder 133, and apply the division lemma to get
337 = 133 x 2 + 71
We consider the new divisor 133 and the new remainder 71,and apply the division lemma to get
133 = 71 x 1 + 62
We consider the new divisor 71 and the new remainder 62,and apply the division lemma to get
71 = 62 x 1 + 9
We consider the new divisor 62 and the new remainder 9,and apply the division lemma to get
62 = 9 x 6 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 470 and 807 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(62,9) = HCF(71,62) = HCF(133,71) = HCF(337,133) = HCF(470,337) = HCF(807,470) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 1, we apply the division lemma to 621 and 1, to get
621 = 1 x 621 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 621 is 1
Notice that 1 = HCF(621,1) .
