Highest Common Factor of 720, 10, 775, 690 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 10, 775, 690 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 10, 775, 690 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 720, 10, 775, 690 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 720, 10, 775, 690 is 5.

HCF(720, 10, 775, 690) = 5

HCF of 720, 10, 775, 690 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 720, 10, 775, 690 is 5.

Highest Common Factor of 720,10,775,690 using Euclid's algorithm

Step 1: Since 720 > 10, we apply the division lemma to 720 and 10, to get

720 = 10 x 72 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 720 and 10 is 10

Notice that 10 = HCF(720,10) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 775 > 10, we apply the division lemma to 775 and 10, to get

775 = 10 x 77 + 5

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 5 and 10, to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 10 and 775 is 5

Notice that 5 = HCF(10,5) = HCF(775,10) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 690 > 5, we apply the division lemma to 690 and 5, to get

690 = 5 x 138 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 690 is 5

Notice that 5 = HCF(690,5) .
