HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 990, 750 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 990, 750 is 10 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 400, 990, 750 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 400, 990, 750 is 10.
HCF(400, 990, 750) = 10
HCF of 400, 990, 750 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 990, 750 is 10.
Highest Common Factor of 400,990,750 is 10
Step 1: Since 990 > 400, we apply the division lemma to 990 and 400, to get
990 = 400 x 2 + 190
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 190 and 400, to get
400 = 190 x 2 + 20
Step 3: We consider the new divisor 190 and the new remainder 20, and apply the division lemma to get
190 = 20 x 9 + 10
We consider the new divisor 20 and the new remainder 10, and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 400 and 990 is 10
Notice that 10 = HCF(20,10) = HCF(190,20) = HCF(400,190) = HCF(990,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 750 > 10, we apply the division lemma to 750 and 10, to get
750 = 10 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 750 is 10
Notice that 10 = HCF(750,10) .
