Given numbers are 424, 231, 765, 670
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(424, 231) = 97944
GCD(424, 231) = ( 424 x 231 ) / 97944
= 424 / 231
= 424
Step2:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
Step3:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
So, Greatest Common Divisor of 424, 231, 765, 670 is 1
