Given numbers are 780, 463, 655, 610
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 463) = 361140
GCD(780, 463) = ( 780 x 463 ) / 361140
= 780 / 463
= 780
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 610) = 610
GCD(1, 610) = ( 1 x 610 ) / 610
= 1 / 610
= 1
So, Greatest Common Divisor of 780, 463, 655, 610 is 1
