HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 385, 740 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 70, 385, 740 is 5 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 70, 385, 740 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 70, 385, 740 is 5.
HCF(70, 385, 740) = 5
HCF of 70, 385, 740 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 70, 385, 740 is 5.
Highest Common Factor of 70,385,740 is 5
Step 1: Since 385 > 70, we apply the division lemma to 385 and 70, to get
385 = 70 x 5 + 35
Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 35 and 70, to get
70 = 35 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 70 and 385 is 35
Notice that 35 = HCF(70,35) = HCF(385,70) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 740 > 35, we apply the division lemma to 740 and 35, to get
740 = 35 x 21 + 5
Step 2: Since the reminder 35 ≠ 0, we apply division lemma to 5 and 35, to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 35 and 740 is 5
Notice that 5 = HCF(35,5) = HCF(740,35) .
