GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 255) = 63495
GCD(747, 255) = ( 747 x 255 ) / 63495
= 747 / 255
= 747
Step2:
LCM(3, 490) = 1470
GCD(3, 490) = ( 3 x 490 ) / 1470
= 3 / 490
= 3
Step3:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
So, Greatest Common Divisor of 747, 255, 490, 986 is 1
