Given numbers are 125, 390, 702, 308
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(125, 390) = 9750
GCD(125, 390) = ( 125 x 390 ) / 9750
= 125 / 390
= 125
Step2:
LCM(5, 702) = 3510
GCD(5, 702) = ( 5 x 702 ) / 3510
= 5 / 702
= 5
Step3:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
So, Greatest Common Divisor of 125, 390, 702, 308 is 1
