HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 972, 918 i.e. 54 the largest integer that leaves a remainder zero for all numbers.

HCF of 972, 918 is 54 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 972, 918 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 972, 918 is 54.

HCF(972, 918) = 54

HCF of 972, 918 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 972, 918 is 54.

Highest Common Factor of 972,918 using Euclid's algorithm

Highest Common Factor of 972,918 is 54

Step 1: Since 972 > 918, we apply the division lemma to 972 and 918, to get

972 = 918 x 1 + 54

Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 54 and 918, to get

918 = 54 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 54, the HCF of 972 and 918 is 54

Notice that 54 = HCF(918,54) = HCF(972,918) .
