Given numbers are 240, 372, 395, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 372) = 7440
GCD(240, 372) = ( 240 x 372 ) / 7440
= 240 / 372
= 240
Step2:
LCM(12, 395) = 4740
GCD(12, 395) = ( 12 x 395 ) / 4740
= 12 / 395
= 12
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 240, 372, 395, 639 is 1
