Given numbers are 438, 830, 273, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 830) = 181770
GCD(438, 830) = ( 438 x 830 ) / 181770
= 438 / 830
= 438
Step2:
LCM(2, 273) = 546
GCD(2, 273) = ( 2 x 273 ) / 546
= 2 / 273
= 2
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 438, 830, 273, 628 is 1
