HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 491, 907 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 491, 907 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 790, 491, 907 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 790, 491, 907 is 1.
HCF(790, 491, 907) = 1
HCF of 790, 491, 907 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 491, 907 is 1.
Highest Common Factor of 790,491,907 is 1
Step 1: Since 790 > 491, we apply the division lemma to 790 and 491, to get
790 = 491 x 1 + 299
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 299 and 491, to get
491 = 299 x 1 + 192
Step 3: We consider the new divisor 299 and the new remainder 192, and apply the division lemma to get
299 = 192 x 1 + 107
We consider the new divisor 192 and the new remainder 107,and apply the division lemma to get
192 = 107 x 1 + 85
We consider the new divisor 107 and the new remainder 85,and apply the division lemma to get
107 = 85 x 1 + 22
We consider the new divisor 85 and the new remainder 22,and apply the division lemma to get
85 = 22 x 3 + 19
We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get
22 = 19 x 1 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 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 790 and 491 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(85,22) = HCF(107,85) = HCF(192,107) = HCF(299,192) = HCF(491,299) = HCF(790,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 907 > 1, we apply the division lemma to 907 and 1, to get
907 = 1 x 907 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 907 is 1
Notice that 1 = HCF(907,1) .
