Given numbers are 240, 730, 787, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 730) = 17520
GCD(240, 730) = ( 240 x 730 ) / 17520
= 240 / 730
= 240
Step2:
LCM(10, 787) = 7870
GCD(10, 787) = ( 10 x 787 ) / 7870
= 10 / 787
= 10
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 240, 730, 787, 685 is 1
