HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 945 i.e. 35 the largest integer that leaves a remainder zero for all numbers.

HCF of 70, 945 is 35 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, 945 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, 945 is 35.

HCF(70, 945) = 35

HCF of 70, 945 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 70, 945 is 35.

Highest Common Factor of 70,945 using Euclid's algorithm

Highest Common Factor of 70,945 is 35

Step 1: Since 945 > 70, we apply the division lemma to 945 and 70, to get

945 = 70 x 13 + 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 945 is 35

Notice that 35 = HCF(70,35) = HCF(945,70) .
