HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 358, 697, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 358, 697, 949 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 358, 697, 949 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 358, 697, 949 is 1.
HCF(358, 697, 949) = 1
HCF of 358, 697, 949 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 358, 697, 949 is 1.
Highest Common Factor of 358,697,949 is 1
Step 1: Since 697 > 358, we apply the division lemma to 697 and 358, to get
697 = 358 x 1 + 339
Step 2: Since the reminder 358 ≠ 0, we apply division lemma to 339 and 358, to get
358 = 339 x 1 + 19
Step 3: We consider the new divisor 339 and the new remainder 19, and apply the division lemma to get
339 = 19 x 17 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 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 358 and 697 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(339,19) = HCF(358,339) = HCF(697,358) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 949 > 1, we apply the division lemma to 949 and 1, to get
949 = 1 x 949 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 949 is 1
Notice that 1 = HCF(949,1) .
