Given numbers are 130, 298, 807, 747
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(130, 298) = 19370
GCD(130, 298) = ( 130 x 298 ) / 19370
= 130 / 298
= 130
Step2:
LCM(2, 807) = 1614
GCD(2, 807) = ( 2 x 807 ) / 1614
= 2 / 807
= 2
Step3:
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
= 1 / 747
= 1
So, Greatest Common Divisor of 130, 298, 807, 747 is 1
