Given numbers are 485, 121, 486, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 121) = 58685
GCD(485, 121) = ( 485 x 121 ) / 58685
= 485 / 121
= 485
Step2:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 485, 121, 486, 490 is 1
