Given numbers are 862, 288, 642, 759
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 288) = 124128
GCD(862, 288) = ( 862 x 288 ) / 124128
= 862 / 288
= 862
Step2:
LCM(2, 642) = 642
GCD(2, 642) = ( 2 x 642 ) / 642
= 2 / 642
= 2
Step3:
LCM(2, 759) = 1518
GCD(2, 759) = ( 2 x 759 ) / 1518
= 2 / 759
= 2
So, Greatest Common Divisor of 862, 288, 642, 759 is 1
