HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 160, 45, 779 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 160, 45, 779 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 784, 160, 45, 779 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 784, 160, 45, 779 is 1.
HCF(784, 160, 45, 779) = 1
HCF of 784, 160, 45, 779 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 160, 45, 779 is 1.
Highest Common Factor of 784,160,45,779 is 1
Step 1: Since 784 > 160, we apply the division lemma to 784 and 160, to get
784 = 160 x 4 + 144
Step 2: Since the reminder 160 ≠ 0, we apply division lemma to 144 and 160, to get
160 = 144 x 1 + 16
Step 3: We consider the new divisor 144 and the new remainder 16, and apply the division lemma to get
144 = 16 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 784 and 160 is 16
Notice that 16 = HCF(144,16) = HCF(160,144) = HCF(784,160) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 45 > 16, we apply the division lemma to 45 and 16, to get
45 = 16 x 2 + 13
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 13 and 16, to get
16 = 13 x 1 + 3
Step 3: We consider the new divisor 13 and the new remainder 3, and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 45 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(45,16) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 779 > 1, we apply the division lemma to 779 and 1, to get
779 = 1 x 779 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 779 is 1
Notice that 1 = HCF(779,1) .
