Given numbers are 720, 670, 979, 972
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 670) = 48240
GCD(720, 670) = ( 720 x 670 ) / 48240
= 720 / 670
= 720
Step2:
LCM(10, 979) = 9790
GCD(10, 979) = ( 10 x 979 ) / 9790
= 10 / 979
= 10
Step3:
LCM(1, 972) = 972
GCD(1, 972) = ( 1 x 972 ) / 972
= 1 / 972
= 1
So, Greatest Common Divisor of 720, 670, 979, 972 is 1
