Given numbers are 387, 228, 986, 870
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 228) = 29412
GCD(387, 228) = ( 387 x 228 ) / 29412
= 387 / 228
= 387
Step2:
LCM(3, 986) = 2958
GCD(3, 986) = ( 3 x 986 ) / 2958
= 3 / 986
= 3
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 387, 228, 986, 870 is 1
