HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 70, 357, 354 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 70, 357, 354 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 742, 70, 357, 354 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 742, 70, 357, 354 is 1.
HCF(742, 70, 357, 354) = 1
HCF of 742, 70, 357, 354 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 70, 357, 354 is 1.
Highest Common Factor of 742,70,357,354 is 1
Step 1: Since 742 > 70, we apply the division lemma to 742 and 70, to get
742 = 70 x 10 + 42
Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 42 and 70, to get
70 = 42 x 1 + 28
Step 3: We consider the new divisor 42 and the new remainder 28, and apply the division lemma to get
42 = 28 x 1 + 14
We consider the new divisor 28 and the new remainder 14, and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 742 and 70 is 14
Notice that 14 = HCF(28,14) = HCF(42,28) = HCF(70,42) = HCF(742,70) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 357 > 14, we apply the division lemma to 357 and 14, to get
357 = 14 x 25 + 7
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 7 and 14, to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 14 and 357 is 7
Notice that 7 = HCF(14,7) = HCF(357,14) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 354 > 7, we apply the division lemma to 354 and 7, to get
354 = 7 x 50 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 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 7 and 354 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(354,7) .
