Given numbers are 408, 668, 757, 769
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 668) = 68136
GCD(408, 668) = ( 408 x 668 ) / 68136
= 408 / 668
= 408
Step2:
LCM(4, 757) = 3028
GCD(4, 757) = ( 4 x 757 ) / 3028
= 4 / 757
= 4
Step3:
LCM(1, 769) = 769
GCD(1, 769) = ( 1 x 769 ) / 769
= 1 / 769
= 1
So, Greatest Common Divisor of 408, 668, 757, 769 is 1
