Given numbers are 490, 475, 308, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(490, 475) = 46550
GCD(490, 475) = ( 490 x 475 ) / 46550
= 490 / 475
= 490
Step2:
LCM(5, 308) = 1540
GCD(5, 308) = ( 5 x 308 ) / 1540
= 5 / 308
= 5
Step3:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
So, Greatest Common Divisor of 490, 475, 308, 187 is 1
