Given numbers are 240, 612, 661, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 612) = 12240
GCD(240, 612) = ( 240 x 612 ) / 12240
= 240 / 612
= 240
Step2:
LCM(12, 661) = 7932
GCD(12, 661) = ( 12 x 661 ) / 7932
= 12 / 661
= 12
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 240, 612, 661, 490 is 1
