Given numbers are 828, 464, 437, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(828, 464) = 96048
GCD(828, 464) = ( 828 x 464 ) / 96048
= 828 / 464
= 828
Step2:
LCM(4, 437) = 1748
GCD(4, 437) = ( 4 x 437 ) / 1748
= 4 / 437
= 4
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 828, 464, 437, 642 is 1
