Given numbers are 144, 730, 581, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(144, 730) = 52560
GCD(144, 730) = ( 144 x 730 ) / 52560
= 144 / 730
= 144
Step2:
LCM(2, 581) = 1162
GCD(2, 581) = ( 2 x 581 ) / 1162
= 2 / 581
= 2
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 144, 730, 581, 398 is 1
