Given numbers are 280, 780, 675, 436
The list of prime factors of all numbers are
Prime factors of 280 are 2 x 2 x 2 x 5 x 7
Prime factors of 780 are 2 x 2 x 3 x 5 x 13
Prime factors of 675 are 3 x 3 x 3 x 5 x 5
Prime factors of 436 are 2 x 2 x 109
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 280, 780, 675, 436
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 780) = 10920
GCD(280, 780) = ( 280 x 780 ) / 10920
= 280 / 780
= 280
Step2:
LCM(20, 675) = 2700
GCD(20, 675) = ( 20 x 675 ) / 2700
= 20 / 675
= 20
Step3:
LCM(5, 436) = 2180
GCD(5, 436) = ( 5 x 436 ) / 2180
= 5 / 436
= 5
So, Greatest Common Divisor of 280, 780, 675, 436 is 1
