Given numbers are 115, 255, 758, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 255) = 5865
GCD(115, 255) = ( 115 x 255 ) / 5865
= 115 / 255
= 115
Step2:
LCM(5, 758) = 3790
GCD(5, 758) = ( 5 x 758 ) / 3790
= 5 / 758
= 5
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 115, 255, 758, 402 is 1
