HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 664, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 664, 475 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 787, 664, 475 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 787, 664, 475 is 1.
HCF(787, 664, 475) = 1
HCF of 787, 664, 475 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 664, 475 is 1.
Highest Common Factor of 787,664,475 is 1
Step 1: Since 787 > 664, we apply the division lemma to 787 and 664, to get
787 = 664 x 1 + 123
Step 2: Since the reminder 664 ≠ 0, we apply division lemma to 123 and 664, to get
664 = 123 x 5 + 49
Step 3: We consider the new divisor 123 and the new remainder 49, and apply the division lemma to get
123 = 49 x 2 + 25
We consider the new divisor 49 and the new remainder 25,and apply the division lemma to get
49 = 25 x 1 + 24
We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get
25 = 24 x 1 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 664 is 1
Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(49,25) = HCF(123,49) = HCF(664,123) = HCF(787,664) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 1, we apply the division lemma to 475 and 1, to get
475 = 1 x 475 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 475 is 1
Notice that 1 = HCF(475,1) .
