Given numbers are 155, 492, 758, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 492) = 76260
GCD(155, 492) = ( 155 x 492 ) / 76260
= 155 / 492
= 155
Step2:
LCM(1, 758) = 758
GCD(1, 758) = ( 1 x 758 ) / 758
= 1 / 758
= 1
Step3:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
So, Greatest Common Divisor of 155, 492, 758, 403 is 1
