GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(186, 490) = 45570
GCD(186, 490) = ( 186 x 490 ) / 45570
= 186 / 490
= 186
Step2:
LCM(2, 470) = 470
GCD(2, 470) = ( 2 x 470 ) / 470
= 2 / 470
= 2
Step3:
LCM(2, 636) = 636
GCD(2, 636) = ( 2 x 636 ) / 636
= 2 / 636
= 2
So, Greatest Common Divisor of 186, 490, 470, 636 is 2
