HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 750, 435, 278 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 750, 435, 278 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 750, 435, 278 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 750, 435, 278 is 1.
HCF(750, 435, 278) = 1
HCF of 750, 435, 278 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 750, 435, 278 is 1.
Highest Common Factor of 750,435,278 is 1
Step 1: Since 750 > 435, we apply the division lemma to 750 and 435, to get
750 = 435 x 1 + 315
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 315 and 435, to get
435 = 315 x 1 + 120
Step 3: We consider the new divisor 315 and the new remainder 120, and apply the division lemma to get
315 = 120 x 2 + 75
We consider the new divisor 120 and the new remainder 75,and apply the division lemma to get
120 = 75 x 1 + 45
We consider the new divisor 75 and the new remainder 45,and apply the division lemma to get
75 = 45 x 1 + 30
We consider the new divisor 45 and the new remainder 30,and apply the division lemma to get
45 = 30 x 1 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 750 and 435 is 15
Notice that 15 = HCF(30,15) = HCF(45,30) = HCF(75,45) = HCF(120,75) = HCF(315,120) = HCF(435,315) = HCF(750,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 278 > 15, we apply the division lemma to 278 and 15, to get
278 = 15 x 18 + 8
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 8 and 15, to get
15 = 8 x 1 + 7
Step 3: We consider the new divisor 8 and the new remainder 7, and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 15 and 278 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(278,15) .
