Given numbers are 141, 146, 156, 280
The list of prime factors of all numbers are
Prime factors of 141 are 3 x 47
Prime factors of 146 are 2 x 73
Prime factors of 156 are 2 x 2 x 3 x 13
Prime factors of 280 are 2 x 2 x 2 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 141, 146, 156, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(141, 146) = 20586
GCD(141, 146) = ( 141 x 146 ) / 20586
= 141 / 146
= 141
Step2:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 141, 146, 156, 280 is 1
