HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 357, 970, 356 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 357, 970, 356 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 357, 970, 356 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 357, 970, 356 is 1.
HCF(357, 970, 356) = 1
HCF of 357, 970, 356 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 357, 970, 356 is 1.
Highest Common Factor of 357,970,356 is 1
Step 1: Since 970 > 357, we apply the division lemma to 970 and 357, to get
970 = 357 x 2 + 256
Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 256 and 357, to get
357 = 256 x 1 + 101
Step 3: We consider the new divisor 256 and the new remainder 101, and apply the division lemma to get
256 = 101 x 2 + 54
We consider the new divisor 101 and the new remainder 54,and apply the division lemma to get
101 = 54 x 1 + 47
We consider the new divisor 54 and the new remainder 47,and apply the division lemma to get
54 = 47 x 1 + 7
We consider the new divisor 47 and the new remainder 7,and apply the division lemma to get
47 = 7 x 6 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 357 and 970 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(47,7) = HCF(54,47) = HCF(101,54) = HCF(256,101) = HCF(357,256) = HCF(970,357) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 356 > 1, we apply the division lemma to 356 and 1, to get
356 = 1 x 356 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 356 is 1
Notice that 1 = HCF(356,1) .
