Given numbers are 280, 475, 356, 156
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 475 are 5 x 5 x 19
Prime factors of 356 are 2 x 2 x 89
Prime factors of 156 are 2 x 2 x 3 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 280, 475, 356, 156
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 475) = 26600
GCD(280, 475) = ( 280 x 475 ) / 26600
= 280 / 475
= 280
Step2:
LCM(5, 356) = 1780
GCD(5, 356) = ( 5 x 356 ) / 1780
= 5 / 356
= 5
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 280, 475, 356, 156 is 1
