Given numbers are 642, 457, 290, 716
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 457) = 293394
GCD(642, 457) = ( 642 x 457 ) / 293394
= 642 / 457
= 642
Step2:
LCM(1, 290) = 290
GCD(1, 290) = ( 1 x 290 ) / 290
= 1 / 290
= 1
Step3:
LCM(1, 716) = 716
GCD(1, 716) = ( 1 x 716 ) / 716
= 1 / 716
= 1
So, Greatest Common Divisor of 642, 457, 290, 716 is 1
