Given numbers are 408, 284, 353, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 284) = 28968
GCD(408, 284) = ( 408 x 284 ) / 28968
= 408 / 284
= 408
Step2:
LCM(4, 353) = 1412
GCD(4, 353) = ( 4 x 353 ) / 1412
= 4 / 353
= 4
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 408, 284, 353, 647 is 1
