Given numbers are 870, 486, 249, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 486) = 70470
GCD(870, 486) = ( 870 x 486 ) / 70470
= 870 / 486
= 870
Step2:
LCM(6, 249) = 498
GCD(6, 249) = ( 6 x 249 ) / 498
= 6 / 249
= 6
Step3:
LCM(3, 193) = 579
GCD(3, 193) = ( 3 x 193 ) / 579
= 3 / 193
= 3
So, Greatest Common Divisor of 870, 486, 249, 193 is 1
