Given numbers are 858, 645, 141, 776
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 645) = 184470
GCD(858, 645) = ( 858 x 645 ) / 184470
= 858 / 645
= 858
Step2:
LCM(3, 141) = 141
GCD(3, 141) = ( 3 x 141 ) / 141
= 3 / 141
= 3
Step3:
LCM(3, 776) = 2328
GCD(3, 776) = ( 3 x 776 ) / 2328
= 3 / 776
= 3
So, Greatest Common Divisor of 858, 645, 141, 776 is 1
