Given numbers are 862, 642, 579, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 642) = 276702
GCD(862, 642) = ( 862 x 642 ) / 276702
= 862 / 642
= 862
Step2:
LCM(2, 579) = 1158
GCD(2, 579) = ( 2 x 579 ) / 1158
= 2 / 579
= 2
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 862, 642, 579, 790 is 1
