HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 721, 907 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 721, 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 354, 721, 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 354, 721, 907 is 1.
HCF(354, 721, 907) = 1
HCF of 354, 721, 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 354, 721, 907 is 1.
Highest Common Factor of 354,721,907 is 1
Step 1: Since 721 > 354, we apply the division lemma to 721 and 354, to get
721 = 354 x 2 + 13
Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 13 and 354, to get
354 = 13 x 27 + 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 354 and 721 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(354,13) = HCF(721,354) .
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) .
