Given numbers are 248, 768, 641, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(248, 768) = 23808
GCD(248, 768) = ( 248 x 768 ) / 23808
= 248 / 768
= 248
Step2:
LCM(8, 641) = 5128
GCD(8, 641) = ( 8 x 641 ) / 5128
= 8 / 641
= 8
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 248, 768, 641, 680 is 1
