Given numbers are 390, 455, 291, 412
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 455) = 2730
GCD(390, 455) = ( 390 x 455 ) / 2730
= 390 / 455
= 390
Step2:
LCM(65, 291) = 18915
GCD(65, 291) = ( 65 x 291 ) / 18915
= 65 / 291
= 65
Step3:
LCM(1, 412) = 412
GCD(1, 412) = ( 1 x 412 ) / 412
= 1 / 412
= 1
So, Greatest Common Divisor of 390, 455, 291, 412 is 1
