Given numbers are 812, 688, 348, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 688) = 139664
GCD(812, 688) = ( 812 x 688 ) / 139664
= 812 / 688
= 812
Step2:
LCM(4, 348) = 348
GCD(4, 348) = ( 4 x 348 ) / 348
= 4 / 348
= 4
Step3:
LCM(4, 861) = 3444
GCD(4, 861) = ( 4 x 861 ) / 3444
= 4 / 861
= 4
So, Greatest Common Divisor of 812, 688, 348, 861 is 1
