GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 884) = 141440
GCD(640, 884) = ( 640 x 884 ) / 141440
= 640 / 884
= 640
Step2:
LCM(4, 892) = 892
GCD(4, 892) = ( 4 x 892 ) / 892
= 4 / 892
= 4
Step3:
LCM(4, 830) = 1660
GCD(4, 830) = ( 4 x 830 ) / 1660
= 4 / 830
= 4
So, Greatest Common Divisor of 640, 884, 892, 830 is 2
